Dakota Johnson's 'Fifty Shades of Grey' dirty little secret: Anastasia Steele beauty 'no shame' in sexually 'breaking men down' alongside Christian Grey hottie Jamie Dornan

Dakota Johnson was recently cast as Anastasia Steele in E.L. James' highly-anticipated film adaptation of "Fifty Shades of Grey." So, how is the 24-year-old beauty capable of filming such raunchy sex scenes alongside Christian Grey heartthrob Jamie Dornan?

"I don't have any problem doing anything," Johnson revealed to ELLE magazine. "The secret is I have no shame." 

The stunning model/actress continues, "Reading the book, I found myself more interested in the ways they were breaking each other down emotionally than the sex scenes... I think there's a part of a woman that wants to be the thing that breaks a man down." 

Some "Fifty Shades" fans doubted it at first, but it sounds like Johnson's perfect for the S&M-inspired role!

The former "Ben and Kate" starlet appears on the March 2014 cover issue of ELLE. Get more info here.
