After getting hitched to Adam Brody (or Seth Cohen from The O.C., because we still live in the early 2000s in our heads), Leighton Meester (or Blair Waldorf from Gossip Girl) has been keeping a seriously low profile. But now she's back — and more stylin' than ever. At last night's premiere party for her new Broadway show Of Mice and Men (which also stars mega-babe James Franco), Leighton nailed it in a navy Versace gown. The look was topped off with messy locks and a subtle smokey eye. Clearly, married life is working out for her — and Blair would most definitely be proud.
