Victoria Beckham is reportedly in line to design the outfits for the 'Fifty Shades of Grey' film.

The 39-year-old fashion designer appears to be in demand to create a range of sexy clothes for lead characters Christian Grey and Anastasia Steele for the racy film which will be based on E.L. James book.

A source told the Daily Star newspaper: ''Fifty Shades is going to be more than a movie. We are hoping for spin-offs in fashion and music. Victoria is front runner.''

Universal chiefs are also reportedly considering designers Dolce and Gabbana, Diane Von Furstenberg, Calvin Klein and Marc Jacobs for the film which is being directed by Sam Taylor-Wood.

Victoria Beckham - who is married to retired soccer star David Beckham - is a fan of the erotic novel and even got her mother, Jackie Adams, a copy.

The former Spice Girl previously said: ''I'm halfway through the second one. I even bought my mum the book.

''But every time she tries to engage in conversation about it, I kind of dodge the subject. I don't really want to talk to my mother about S&M.''
