Bella Thorne and Zendaya didn't really get along in the beginning of their show, Shake It Up. They eventually were able to move passed it and are still friends to this day.
"Zendaya and I were put in a very unfortunate position where we were kind of forced to compete against each other, which made the whole first season of the show just very awkward for us," Bella told J-14. "We wanted to love each other, but yet we were constantly being put against each other. It was, 'Who's better at this?' and 'Who's better at that?' And then second season we kind of just had this tell-all talk where we started crying and really just put everything out there on the table, and that's when we became best friends."
Dove Cameron and Ryan McCartan were co-stars on Liv and Maddie and although the two ended up having a two-year relationship off-screen together before calling it quits, their love story almost didn't happen at all, since they didn't like each other very much at first.
"My first impression was that she was arrogant and self-righteous. It was definitely not love at first sight. To set the record straight, I don’t think I’ve ever been more wrong about a person. Once I got to know her, I learned her depth of character, how sweet and emotionally raw she is," Ryan said.
"We both insulted each other within the first five minutes of being in one another’s presence," Dove added. "But then five minutes after that, when the Liv and Maddie producers told us to 'Stand really close, look in each other’s eyes and act like you like each other,' we found that we had quite a different chemical reaction to one another."
Miley Cyrus and Emily Osment and played the best of friends on Hannah Montana but in real life, there were times when the girls just didn't get along, which Miley spilled in her book, Miles To Go, the singer revealed that she and Emily used to get in huge fights, and even hated each other.
"The show felt real to me, and I wanted my relationship with Lilly to feel real too. I knew it didn’t have to – show business is show business – but I was disappointed. There were times when I didn’t think we could ever be friends. We just couldn’t figure out how to get along," Miley wrote.
Ashley Tisdale admitted that she didn't get along with her High School Musical co-star and on-screen brother Lucas Grabeel because Ash was in character as Sharpay.
"We would hardly talk to each other. When I was auditioning for [mean girl] Sharpay, I screen-tested with him and I was acting like Sharpay. I think he was like, ‘Who is this girl telling me what to do?,'" she said.
Victoria Justice and Ariana Grande were rumored to not along while working on Victorious together, and things got even more intense when Ari did an interview saying she was bullied by someone she once worked it. People assumed it was Victoria, but she went on to explain that this simply wasn't true.
"So basically, there was an article where [Ariana] had said that she was bullied on set, and the magazine basically alluded to it being me. Once the article came out - actually before it came out -- she texted me privately, and she was like, ‘Oh my gosh, I am so sorry. You know how the media twists words. I was not talking about you obviously, I was talking about someone on Broadway I had worked with.’ But once it got out there everyone thought that I was this bully and mean to her, which couldn’t be further from the truth. Sure, we've had our different, but at the end of the day, everyone on the the cast of Victorious was a family," Victoria said. The cast even all reunited for a super fun, onesie-slumber party, so it seems all really is well.
Naya Rivera and Lea Michele were friends during the beginning of their days on Glee together, but as the series went on, their friendship shattered, which Naya wrote about in her memoir, Sorry Not Sorry: Dreams, Mistakes, and Growing Up. She even said that Lea was the one who leaked a story to the press about Naya being fired from the show, which never actually ended up happening. Yikes.
Blake Lively and Leighton Meester played BFFs Serena and Blair on Gossip Girl, but IRL, the girls aren't really friends anymore, a source spilled.
"After something of a thaw in their relationship during the final two seasons of Gossip Girl, Leighton and Blake don’t speak anymore. It’s simply a matter of both of them being happy not to have to spend 18 hours a day with each other, but the friendship they struggled to build at the end of Gossip Girl has evaporated and they continue to stay as far away from each other as possible," this source said. Ouch!
Jennette McCurdy and Ariana Grande were rumored to not get along toward the end of Sam and Cat, but Jennette set the record straight and said there is no actual tension between, they just sometimes wouldn't get along, like sisters do.
"I just feel that, you know Ariana and I were and are extremely close and very like-minded in a lot of different ways. I think we butted heads at times but in a very sisterly way. She knows me so well and I know her so well," Jennette said.
