Watch your back, S. While you were off in Paris shooting your Chanel handbag campaign, B snagged a fabulous designer gig of her own.

Leighton Meester is the face of Missoni's Spring/Summer 2011 ad campaign, and the first shots show the 24-year-old Gossip Girl actress riding a rocking horse in a sheer hiked-up-to-there Missoni mini. The playful pics are a major departure from her onscreen character, Blair Waldorf, who wouldn’t be caught dead smiling on a plastic toy pony.

Now the fashion world is waiting with baited breath for photos from Blake Lively's Chanel ad campaign. Perhaps she'll one up her costar by appearing on a real horse? At the very least we expect it to be tres chic.
