Best known as Blair on Gossip Girl, Leighton Meester also appears in Country Strong (check out star Gwyneth Paltrow's CMA Awards performance from last night).
Was her fashion sense strong enough to take on Katherine Heigl's, though? That's for you to say. With Katie's sapphire Farah Angsana gown, it could be tough.
Leighton certainly holds her own in a trailing, draped Emilio Pucci gown, Cathy Waterman jewelry and Jimmy Choo sandals, but whose dress do you prefer?
Who looked better at the CMA Awards?
