This week, Rita Ora opened up about her upcoming role as Christian Grey's sister in the "Fifty Shades of Grey" movie. If fans had their way, Ora may have embodied Matt Bomer's adopted sis; the "White Collar" actor explained his reaction to this demand in a recent interview.

Ora has a short acting resumé, including an uncredited racer role in "Fast & Furious 6," but that didn't stop her from landing the role of Mia.

"She's honestly one of the ones that loves her brother for whatever," Ora told MTV News. "She doesn't know about his fantasies yet, but she's extremely involved and loves him and she studies in France, speaks French, and it was a good learning curve for me."

The singer-turned-actress found herself working hard for "Fifty Shades of Grey," especially when it came to French.

"I prepped for the role by learning some French first of all, by learning an American accent and by really just not being me," Ora explained. "I had a brown wig on, and I was being the smart girl that came from French school to see her family, so it was just a lot of dedication. It was like going back to school."

Ora also said she got along with Dakota Johnson, who plays the lead of Anastasia Steele.

"Working with Dakota was extremely fun," Ora revealed. "She's just so gorgeous so it kind of distracts you a little bit, but I mean she's a really great great ... She's an amazing actress so I'm like learning things from her."  

Some fans wanted Bomer to star opposite the ever-so-fun Johnson, especially after the studio announced Charlie Hunnam's departure. There was an even a Change.org petition to have him and Alexis Bledel for the leads.

"Obviously, I'm incredibly flattered that so many people thought of me," Bomer told Details. "To be honest with you, I've never read any of the books so I don't know what it was that tipped people off that way or made them think of me, but it was sort of like this really strange and interesting cloud that came in and went away I guess. I'm sure it's great though. I bet the movie is going to be amazing."

Apparently, Bomer missed out on some good times.

"Offset there's always shenanigans going on, always someone getting picked on, but it's always having a good time," Ora continued. "You don't want to work under a pressured environment especially when you're making something creative, but it was incredible. I would do it all over again."

"'Fifty Shades of Grey" premieres Feb. 13, 2015.
