Blake & Leighton's GG Event Looks

Gossip Girl's main gals Leighton Meester and Blake Lively were both out to celebrate the 100th episode of the show earlier in the week.

Leighton was pretty in her white Balmain dress, while Blake looked beautiful in a bust-baring Marchesa number, teamed with Lorraine Schwartz jewels.

It was a completely different look for Blake at the Barney's Window Unveiling, her going for a masculine, yet v. feminine look in her royal blue Elie Saab suit.
