Anne Hathaway sports that lovely big smile on the cover of the January 2013 cover of Glamour US, which was shot by Alexei Hay.

Sporting a fun, funky look, the actress wears a Monrow tank and Clover Canyon briefs on the cover, while inside she wears the stunning yellow Alexander McQueen gown recently worn by Rosamund Pike.

In the January 2013 Glamour issue, which is out now, Anne opens up about her husband, her dramatic weight loss, her hair, a cause she wants you to know about and why she wants you to just dance.

On her marriage to Adam Shulman: “I feel like I’ve found my other half, and I’m so excited about getting to love him for the rest of our lives. I would never have gotten married if it weren’t for him. You have to want to be married to someone. You have to feel that reciprocated. Marriage for marriage’s sake doesn’t make any sense to me, and I found someone with whom I could put my money where my mouth is, I guess.”

On her hubby: “He’s a good man. He’s beyond intelligent. He loves fearlessly. His beliefs are beautiful. He’s my best friend. I love him. I just feel that I have the greatest husband in the world for me. You know, we get a lot of pressure to define ourselves as women by how wild we are: How many guys did you sleep with? How drunk did you get? And we all bow to that. We’ve all done that walk of shame at one point or another.”

On her dramatic weight loss: “I still feel the stress over ‘Am I thin enough? Am I too thin? Is my body the right shape?’ There’s an obsessive quality to it that I thought I would’ve grown out of by now. It’s an ongoing source of shame for me.”

On the One Billion Rising campaign: “It’s hard to wrap my head around the fact that a billion women have been raped or beaten, just the enormity of that. When I was in college, I’d heard that one in four women would be raped, and I thought, God, that means I must know someone who was raped. Sure enough, I found out a week later that a friend had been. A billion is too big because one is too big.”
