Anne Hathaway's Slimming Secret

What's the secret of Anne Hathaway's new single-girl glow?

The Rachel Getting Married star puts it all down to her new vegan diet.
 
During a recent appearance on The Late Show With David Letterman, Anne praised her meat- and dairy-free regime, saying, "I have more energy, and my skin looks better."
 
A source close to Anne tells OK! she's also hooked on organic health line Karen & Sisters. "She loves the Tokyo soba noodles, dumplings and veggie turkey," the insider says.

But there's a downside! At brunch a few days earlier at NYC's Paris Commune restaurant, Anne, 25, could only eat spinach and melon while her friends chowed down on carbs.

The Devil Wears Prada star has been back on the market since she split with long-term boyfriend Raffaello Follieri just before he was arrested on fraud charges in June.

Would you go vegan like Anne Hathaway to slim down?

No way, I love burgers!
Sure, I'd try it!
