NATE THROWS A VALENTINE’S DAY BASH / ST. VINCENT PERFORMS — It’s Valentine’s Day on the Upper East Side and Blair(Leighton Meester) can’t resist playing cupid for someone she loves. Georgina (Michelle Tratchenberg) is intent on stirring up more drama, so she decides to crash Nate’s (Chace Crawford) Valentine’s Day party. Meanwhile, Serena (Blake Lively) is shocked by something she witnesses at the party. Penn Badgley, Ed Westwick, Kaylee DeFer, Kelly Rutherford and Matthew Settle also star

Blair (Leighton Meester)’s all dolled-up in red – and, it appears, back home in NYC – and Dan humphrey (Penn Badgley) is about to go in for the kill. Hoooo wahhh!

The only troubling part? B’s posture! She looks a little like the wind’s been knocked outta her sails… (Maybe it’s that loveless marriage she’s currently strapped into? Yeah, solid guess.)
