Kim Kardashian and Bar Refaeli Tweet About ’50 Shades of Grey’ (PHOTOS)

Two of the sexiest women in Hollywood have succumbed to Hollywood’s 50 Shades of Grey obsession: Kim Kardashian, 31, and Bar Refaeli, 27!

Kim tweeted this photo of the book Wednesday night with the caption: “Should I or shouldn’t I?”

This prompted the model– and Maxim’s hottest woman of 2012– to tweet Kim some words of encouragement:

“I’m already in the second one. I think that answers it.”

Here’s hoping the reality mogul took Bar’s advice! Kim certainly wouldn’t be alone. Take a look at the gallery above to see other stars who can’t get enough of the 50 Shades trilogy.

It’s not just girls who have heard about the sexy novel. Check out what Snow White and the Huntsman star Chris Hemsworth had to say about the “trashy” book here:
