We're enjoying the Monday night CW block of One Tree Hill and Life Unexpected.

But it's still safe to say we're giddy over the March 8 return of Gossip Girl. You shouldn't have to ask why - you have seen Serena and listened to every word out of Chuck's mouth, right? - but quotes from the trailer below are reason enough:

• Tell me you didn't sleep with your ex-husband.
• Just so you know, I'm not wearing any underwear.

Who said what to whom? Find out below, and then check out our Gossip Girl spoilers section to find out more about what's to come:
