There's more casting rumors for the movie "Fifty Shades of Grey" and it's a bit shocking. According to Marie Claire, a British newspaper got the inside scoop on auditions for actors and actresses to land roles in the highly anticipated movie.

A source allegedly told the Sun newspaper that model Cara Delevingne has auditioned for a secondary role in "Fifty Shades of Grey." the 20-year-old got into acting when she cast in "Anna Karenina," as Princess Sorokina, starring alongside actress Kiera Knightley.

"Cara is a front-runner for a part," the source told the newspaper. "She's desperate to get the gig and has always said that she wanted to be taken seriously as an actress."

If you remember Sam Taylor-Johnson's husband, Aaron Taylor-Johnson also starred in "Anna Karenina" as Vronsky and apparently she is trying to use that connection to land in the "Fifty Shades" movie.

"[Cara] is a global icon now and a good actress as well and Sam wants her in the movie - though which part exactly hasn't been established," the source continued. "[Her] agent has also been talking to Kelly Marcel, the screenplay writer. And if need be, a strong role will be written in for her."

This rumor sounds very-fetched. Delevingne was never in talks to be in the movie amongst fans and it seems a bit fishy that Marcel or E.L. James is going to add a role just for her.

Delevingne did send out tweet urging her fans not to listen to everything they hear in the press. It wasn't clear what she was referring to. The tweet could have been directed towards the latest "Fifty Shades" rumor or, as Entertainment Wise reports, it could have been about another report that she was cast in the British movie "Kids in Love."

A source reportedly told the Daily Mail that: "It will be Cara's big screen role, so she's really excited about it and is eager to make sure that she does a good job. Her name in itself will obviously be a big draw for the film too."

Do you think the latest casting rumor is true?
