Eat your heart out, boys!

The Twilight Saga's Ashley Greene sucks face with big screen bombshell Olivia Wilde in the upcoming flick Butter– and she kisses and tells about the steamy makeout session in the March 2012 issue of Lucky.

Breaking Celebrity News has all the details!

"It wasn't that awkward," Greene dishes about their love scene. "It's the same idea when you're having to kiss a male costar and it's not real. Olivia is such a cool chick and very professional. So we were just messing around and cracking up in between scenes, and it ended up being really fun.

"And now I'm the envy of every straight male everywhere!" she added with a smile splashed on her face.

Ashley, who has been romantically linked to Joe Jonas, Chace Crawford and Reeve Carney, also reveals that her career, not love, is the most important thing in her life right now.

"I'm so laser-focused on my career, because when you're dealt these cards, if you don't kind of run with it, then you're an idiot," she says about why she isn't in a serious relationship right now.
