Leighton Meester new look

Leighton Meester new look- How's this for a showdown: a real-life royal versus Gossip Girl's Queen B.?!
Kate Middleton stepped out in a stunning, rose sequined Jenny Packham dress, J.K. Bennett clutch and peep-toe heels Thursday night for the Ark charity gala at Kensington Palace.

But her floor-length frock might have had some CW fans doing a double-take. Leighton Meester's alter ego, Blair Waldorf, wore the same dress when she became engaged to Prince Louis this past season in the episode titled "The Princesses and the Frog."
