Can it be? Is Leighton Meester going to join the celebrity designers gang? According to an interview with Vogue UK, it's a possibility: "The more I think about it the more it sounds like something I would want to do. I don't know if it'd be any time soon but I'd really like to work on a collaboration with somebody — I always have ideas for stuff like that." And who might she draw inspiration from? "I really like Cate Blanchett, she's got a really interesting take on things . . . she experiments but is very much a woman. I think Helen Mirren is very sexy and of course I love Audrey Hepburn." Let's not hold our breath, but I would love to someday see what Leighton could create. And judging from her fashion-forward looks, she's got the eye. Step inside to see her 10 best.
