Gossip Girl

Serena, Serena, Serena. If there's one thing we know about Gossip Girl's Blair Waldorf (Leighton Meester, below), it's that she doesn't take kindly to challenges to her social authority. Even if her "enemies" aren't even trying to offend her.

When BFF Serena van der Woodsen (Blake Lively) suddenly becomes the new "It Girl" at school, Blair has a hissy fit - and will do anything to sabotage her and/or Jenny Humphrey, even if it means ruining her own mother's fashion show!

It's just the kind of drama we've come to expect from the CW hit. Follow the link for a recap of this terrific Gossip Girl episode, "The Serena Also Rises" ...
