On One Life to Live, Jessica has been a party to many feuds, conflicts, and high drama -- many of them contained in her own mind! But on tonight's all-new episode of Gossip Girl, Bree Williamson will find herself caught up in an epic feud of a different kind: Blair Waldorf versus Serena van der Woodsen.

Here's what we know about tonight's episode, titled "The Grandfather, Part II" -- classic frenemies Blair and Serena wage another epic battle for superiority, all while Nate's cousin Tripp sweats out his Congressional election night. Bree will play a new It Girl on the scene, Brandeis, whom Blair befriends in order to help her gain the upper hand.

Can Bree's character get one over on the queen bees of New York society? Thus far, nobody else has been able to. But we're looking forward to seeing her swim with the sharks just the same!

What are you hoping to see out of Bree on tonight's show? And what other OLTL actors would you like to see on Gossip Girl?
