Blake Lively and Leighton Meester were looking very happy together on the set of Gossip Girl yesterday. The girls look fabulous as usual, from their trendy outfits right down to their flawless skin and Bella is willing to share one of their secrets with you. We are already counting down the minutes to see the aftermath of Blair and Chuck's scandalous hookup last week. Apparently, tonight's episode will be packed with the usual treats — not only do we get a birthday party for Blair, but the episode will feature 5 songs from the band The Virgins. We can't wait!
