Here is the Gossip Girl Queen B that everyone just loves to hate, Leighton Meester. Last night Leighton appeared in New York City to preview the Christian Dior 2009 Cruise Collection. Leighton was wearing what else, but a gorgeous Dior cocktail dress in this spring’s hottest color, with a banded strapless bodice, and paired with strappy peep-toe Dior pumps. To finish the look, Leighton went minimal on the accessories with a simple necklace accenting her pretty neckline. Leighton Meester plays a fashionista on the Upper East side in ‘Gossip Girl’ and she makes no bones about being a true fashionista in real life. Dior in fact is one of her favorites and you will find a lot of Dior in Leighton’s closet. Leighton has been busy promoting ‘Gossip Girl ’and has just returned from Ital for overseas promotion. As ‘Gossip Girl’ winds down, she is very much looking forward to a little break, but it won’t be long before you see her ruling the roost again on the Upper East Side.
