To celebrate the 100th episode of Gossip Girl the big wigs shunned a celebratory bottle of champers in favour of a big ol’ shindig in New York.

Blake wowed in a stunning 40s-style fringed Marchesa number and Lorraine Schwartz jewels. She added extra sparkle with crystal Versace heels and swept her long locks up to show off statement earrings. With its sheer panelling, that dress should feel a little too risqué but on Blake it just looks gorge.

Kick Ass cutie, Chloe Moretz, looked sweet in a clashing print Stella McCartney dress and heels. After the glamfest that was Blake’s look, we can’t help feeling a little disappointed in Leighton’s, dare we say, cheap looking dress. It might be Balmain but that doesn’t mean it’s nice. You win back some points with your sparkly Jimmy Choos, though.

We’re not keen on this little number, Ed; you look ever so washed out. Was Penn feeling the chill? The stubbly star popped on a woolly scarf over his suit.

Chace opted for a smart suit jacket and open-neck shirt. Looking lovely, Chace. Michelle Trachtenberg’s look also failed to inspire us. This blue jumpsuit would be more suited to a night down the local pub rather than a swanky New York bash
