Leighton, zoe and amanda on what makes them feel glamorous

MATTHIAS VRIENS-MCGRATH FOR GLAMOUR While Manhattan’s Upper East Side might be a world away from the computer-generated forest of _Avatar_, Leighton Meester and Zoe Saldana have one thing in

common along with Amanda Seyfried: their much-coveted style, which has landed them each an April cover of _Glamour_ and a spot on their most glamorous list! Leighton, whom the magazine

names as “Most Stylish”, credits _Gossip Girl_ costume designer Eric Daman for helping her dress both on-and-off screen. “I see what I like from the [runway], but it’s about mixing and

matching. Daily life shouldn’t be a fashion show all the time,” Leighton says. And for Seyfried, named “Most Down-to-Earth”, it isn’t all about the glitz and glam of Hollywood. “A smoky eye

and nice hair are not going to make my night any easier… I have to feel good on the inside to look glamorous,” she says. But, it can help sometimes, as she recalls the _Mamma Mia!_ world

premiere in London. “I was wearing Miu Miu, and I needed to look amazing, because I was starting to really fall in love with my boyfriend [actor Dominic Cooper, her costar in the movie]. I

wanted him to see how glamorous I could be.” It’s not about either clothing or makeup for Zoe. “I love aging! Why would I want to be 21 for the rest of my life? Glamour is about feeling good

in your own skin,” the “Most Elegant” star tells the magazine. Hear more from _Glamour_‘s cover girls in the April issue, on newsstands March 9, or online at glamour.com. TELL US: WHO TOPS
