James' BackgroundEdit

James is first introduced as the pretty boy who only wants to be famous and desperately wants to get out of Minnesota to be a star in California.

He takes the opportunity of Gustavo Rocqué coming to town to do so. Once he gets there, he switches numbers with the others to go last. Kendall, who doesn't let him switch, assures him that stardom is his destiny and he goes in. He joins Kendall, Carlos, and Logan in the brawl with the security guards. He goes to Elwood City with the others and instantly is in love with the city and the boys. James' favorite shirt is his lucky white v-neck, which gets ruined while the boys started squirting each other with fruit water in the recording booth in Big Time Audition.

In Big Time Love Song, James gets a crush on Jo. He is constantly spraying himself with Cuda, which he had an allergic reaction to. He was sneezing constantly and Kelly Wainwright took him to the hosptial. He later tried to flirt with Jo, only to realize (thanks to Camille) that the Cuda had been recalled due to high allergic reactions.

In Big Time Jobs, James tries to get a job as a model/actor. He has Katie be his talent manager and eventually gets a job as an elbow model after being attacked with "handsome."

For the dance, James is shown to be very popular with the girls. While trying to help Logan ask out Camille, he accidentally asks out multiple girls who all say yes. This eventually gets out of hand and all the girls go after him.

James loves wearing bandanas and pushes the group to wear them as well, although they refuse. His obsession with bandanas is so strong that he has a superhero alter-ego called "Bandana Man". According to Carlos, he always gets the girls and declares himself the "pretty one". Though quite self-absorbed most of the time, he is capable of caring for people. This is evident in the episode "Big Time Break ", where he rejects an acting career in order to cheer Camille up.

In Big Time Audition, he said that he's going to marry Nicole Scherzinger from Pussychat Dolls and he's going to do that by being famous, sing at the sold out arena, have 5 houses, and make the girls go crazy over him. In the same episode, when he got fired by Gustavo, he said that he could be a model because he still good looking, or he's going to be a star in a reality show. In Big Time Break, he wants to be an actor and ask Camille to help him to be a great actor, and even go to an audition with her. He said that his face and abs deserve to on TV or the big screen. In Big Time Fans, James' crazy fan said "I wanna take your place in Big Tiime Rush, we tour the world, and I go solo. Start a movie carrier. Marry super hot model. Buy a yacth called S.S. Awesome." and James replied "That's my plan!".

In Big Time Fans, he said that he likes to work out in front of his heroes. So he had the photos of his heroes hanging in the gym wall. His heroes are Abraham Lincoln, David Hasselhoff, and Mahatma Gandhi. He likes to be called "AWESOME" and being awesome. According to him in Big Time Fans, awesomeness is 15% tan, 40% good attitude, 20% bad attitude, and 50% imported hair care product.


James' most prominent personality trait is his vain obsession with himself. He's shown to lead a sort of metrosexual lifestyle and takes great pride on his face, hair and body. James Maslow who played James Diamond in the show said and quote, "James is the lovable narcisist". He's also the most girl crazed of the band mates and has the most experience in the dating world (it is shown in Big Time Dance, how he teach Logan how to ask Camille to the dance with many ways, and how easy it was for him to get a date without even trying). In Big Time Songwriters, when James and Logan can't wrote the lyrics for the "Yeah" song, James said that he usually great with words and Logan replied that he was great when around girls. So, James concluded by saying "Right! My verbal skill work best when I'm charming the ladies." Although, in the show, he is the only one who has never in a relationship. (Jo and Kendall, Logan and Camille, Carlos for an episode have a girlfriend named Sasha, though they broke up at the end of the same episode).

He's also not so bright, this he admits himself in Big Time Sneakers, quote "You know I'm not that clever!". He has been shown to be somewhat dim witted.
In Big Time Job, when he was talking to himself in the mirror, when the mirror James ask "Who's smater than you?" and James replied "A lot of people." In Big Time Guru, when he was trying to make a computer virus to destroy Logan's swagger app, he admits to Camille that he's not bright or not as smart as Logan, therefore can't make the computer virus.

Despite his vain attributes, James cares for his friends deeply. As the oldest, most socially experienced and most confident, he looks out for his fellow band mates and is there to help them in anyway he can.

He's incredibly driven and motivated to reach his dreams no matter what it takes. And many people, besides his friends and family, have notice this. One of them is Hawk's assistant who said "James Diamond, extra pretty, solid voice, driven beyond believe". He has a list of goals that he will do or have to do before he turns 20, this shows how driven he is. This goal is called 'James to do list before 20'. Some of it is to slap a pharaoh, be a weather man, perform on live tv, and being in the greatest band in the history of the world.

According to Katie in Big Time Fans, James is too trusting. He believes everything his fan says to him. He also likes to sign autograph to anything and anyone without reading the text first.

James like to say a word twice for emphasis. For example in Big Time Party "And before you know it we'll be known as "The Hollywood Super Party Kings of Hollywood", or in Big Time Beach Party "All aboard to the Malibu beach party party bus". And after saying that, usually Logan said "You said Hollywood twice" or "You said party twice", which James then replied with "You bet I did."

James, along with Carlos, Kendall, and Logan, like to imagine things that their going to do, like in Big Time Concert when they imagine their first concert that will be in Times Square, or in Big Time Beach Party when they imagine their time on the beach. Kelly said that they like imagining things so much, they once done it for 3 hours. In Big Time Beach Party, James imagining himself surfing. So it might shows that he likes surfing.


James is 6'1" in height and has a athletic physique. He has hazel eyes, long brown hair and a dazzling smile. He prides himself on being the most good looking member. His best assets are his hair and his washboard abs. He really loves his hair. This is shown in Big Time Audition, when the marketing team said "... and possibly shave your heads." James is scared and saying "NO!" while holding his head. In Big Time Fans, James refused to help Jenny because it seems that Jenny burnt all his hair of when they were lab partner in the 8th grade. Logan said "It took almost a whole year for your hair to grow back". He really take good care of his hair to make it look good by using hair care products or by always brushing it with his lucky comb.


He has a good relations with people. Among his friends, family, or anybody else. He is really close to Kendall in making pranks and schemes, this is shown in Big Time Terror. Although this is a rare thing because all the boys are very close to each other. He and Carlos love to play with their food together and sometimes Logan and Kendall consider them immature because of this. He and Carlos also tried to win back their popularity in Palm Woods when they got back from the tour in Welcome Back Big Time. In Big Time Party, it is shown how both James and Carlos love to party and they organize a party that is so awesome, they end up getting the title 'Hollywood Super Party Kings of Hollywood'. He is very close to Logan when it come for relationship tips. This is shown in Big Time Girlfriend and Big Time Dance. Although they did get into a huge fight when James accidentally kissed Camille, but then they had a duel and make peace in the end. Logan and James also attempt to get a lot of money by buying and then selling a limited edition sneakers, but this plan didn't go so well (Big Time Sneakers).

In the series only his father that has been shown, but it is possible that his father and mother are still together because he called his mom for a ride in Big Time Audition. Over the past months Mrs. Knight has act as his parents. She is very protective of him and the boys. James and Katie is very close and sometimes James got very protective over her. This is shown in Big Time Crush, when he said "Katie is very special. She's like a sister to me".

James' relation with the Palm Woods students is good. He has a lot of friends and everyone likes him. He is close to Camille and they care about each other. In Big Time Break, James and Camille go to an audition together and in the same episode, he turned down a role of his dream so he didn't hurt Camille's feeling. In Big Time Girlfriend, James help Camille run lines for an audition. Although they were close they never had romantic feeling towards each other. This is because Camille likes Logan and was once his girlfriend, and James stated in Big Time Dance that Camille is not her tipe. When he and Camille accidentally kissed, both of them feel bad but blame each other. But they didn't get into a fight and try to solve the problem together. James often come to Camille for advice like in Big Time Beach Party, when he thought that the new girl he fell in love with was a mermaid.

James' relationship with Gustavo is considered odd. Gustavo loves or hates the boys equally, including James (in some episodes he said "I hate those dogs"), but somehow he always mention that he can't stand James, mainly because he reminds him of Matthew McConaughey, who he hates a lot, and also because James is self-centered. In Big Time Guru he said that he still cannot stand James and that James still in love with himself.

James and Kelly is very close. If there's any trouble he calls her. In Big Time Love Song, it was Kelly who took him to the doctor and when James realize his allergic reaction to the Cuda Product, Kelly was the one he called.

James has multiple relationships with girls throughout the series and he considered himself an expert on relationship. In Big Time Crush, he said to Katie "When it's time for love, I'm doctor of love". In Big Time Love Song, Carlos stated that James always gets the girl. He is the most experienced in dating and girls just love him. It is very easy for him to get a girl on a date with him. In Big Time Dance, he accidentally ask many girls to the dance when trying to help Logan ask Camille, and all of them said yes. He also stated "Girls like flowers and ME!" He has the most girlfriends out of all the boys in the series but none of them remains constant, they only last an episode. This may show that eventhough he is smooth with the ladies, he is afraid of commitment.


  • James is the last member of Big Time Rush to dress up as a girl, first doing it in Big Time Prom.
  • He has a list of goals to do before he turns 20.
  • He is also currently the only member of the group to not be romantically linked to anyone, along with Carlos. They probably have different reasons, James not being able to choose between his immense amount of fangirls.
  • In the pilot episode, James was the only one that wanted to sing and become famous.
  • In Big Time Party and Big Time Mansion, James, along with Carlos, like to play with their food (making monster face using vegetables or using their Dinosaur shaped chicken as toys).
  • James' autograph is his initials (J.D.) in capital letters with a star between them. Meaning that he really wants to be a star.
  • James and the boys like to imagine exciting things their going to do, like in Big Time Concert and Big Time Beach Party.
  • James played the piano in Big Time Songwriters.
