12 celebs who can’t hide their obsession with Fifty Shades of Grey

5. Hilary Duff

Hilary Duff told Celebuzz she’s totally into Fifty Shades of Grey: “I feel a little dirty reading that book, just with my new baby–but I’m in, I like it,” said Duff, and even gave her own opinions on who should play the leads in the Fifty Shades film. You wouldn’t really expect the angel-faced Cheaper by the Dozen and A Cinderella Story star to be engrossed in an erotic novel, but it’s awesome to be reminded that she’s got an edge to her.
