Without a doubt Anne Hathaway has a killer smile. With shorter cropped hair, her mouth is out of control… in a good way. The 30-year-old is absolutely rocking on the cover of Glamour magazine’s January 2013 issue which was snapped by photographer Alexei Hay. Sporting a tank, briefs and shiny stylin’ Skullcandy headphones, Hathaway glows. Must be the fact she’s in love and a recent newlywed. She wed Adam Shulman this past summer.

“It’s wonderful. 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.” – Anne Hathaway
