Looks like the bitch is hitting the fan next Monday on Gossip Girl.
Or two, to be more precise--as Blair and Serena will use Tripp Archibald's Senate fundraiser (or gala, or launch party, or something) as the background for their latest frenemy feud, and--knowing them--it's unlikely that either will come out on top.
After the jump, check out the extended promo for Monday's episode (November 2, 9 PM, The CW), plus two clips from the episode.
In one, Blair and Serena butt heads over Blair's new blonde "best friend."
In the other, Dan's new favorite blonde tries to hide something from him. What could Olivia have said on Jimmy Fallon that was so bad?
