How Anna Kendrick Made 'Pitch Perfect 3' Co-Star Ruby Rose Self Conscious About 'Fat Fingers' (Exclusive)
Inside the 'Pitch Perfect 3' Premiere

Rose tells TooFab: "I was literally looking at my hands going, 'What?'"

Way to make things aca-awkward on the "Pitch Perfect 3" set, Anna Kendrick.

Ruby Rose told TooFab ahead of the movie's release this Friday that her co-star accidentally made her really self conscious about her fingers while throwing off-the-cuff insults at each other for a scene that didn't make the final cut in the comedy.

"There was a scene that they took out where they were talking about how my band had gone to Yale and they were like, 'Well, they can't be very good' and then they were like, 'Oh, they play instruments and they sing? Well, they must be really mean,'" Rose told TooFab. "And then we were actually pretty nice, so we did an ad-lib where Anna was trying to find things that would be wrong with us and she was like, 'You've got fat fingers' and I literally didn’t know what to do," Rose told TooFab.

"I was literally looking at my hands going, 'What?' And she was like, 'No you really don't have fat fingers, I don't know why I even said that,'" Rose continued. "And I was like, 'That was a really weird thing to say' and she's like, 'I don't even know where that came from.'"

But the gag stuck and it became a recurring joke on set.

"I would be on my phone and someone would walk past me and be like, 'Are you texting or are your fingers too fat?' And I was like, 'Guys! I actually have really thin fingers, like what are you talking about?'"

Rose credited her other co-star, Rebel Wilson, for being the most amusing on set.

"If I were to give an award for being the most witty, it's Rebel," Rose said. "Like for my character to have to keep such a stone, unimpressed and above it all appearance, was next to impossible next to Rebel when she's saying these things to me. It was tough not to laugh."

Especially because Rose was tasked with playing it cool on screen opposite someone she used to idolize on TV in Australia when she was younger.

"I've been a big fan of Rebel for forever," Rose said. "She's been on TV in Australia since I was a kid and she was a kid and I have a tremendous amount of respect for her because I think she's hilarious."

"Growing up in Australia, she was just such a familiar face and she was one of those people that you feel like you know and I had to remind myself, 'Oh, I don't know this person' because I wanted to be like, 'Hey, Rebel!' But then I was like, 'I mean, hi Rebel. Nice to meet you,'" Rose said. "But she was the same. We went super Australian and we were just like, 'Mate, whats up?' and everyone's looking at us like, 'What is going on? Are they even speaking English?' But I think she was happy to have another Aussie on set with her."

"Pitch Perfect 3" opens in theaters this Friday.
