Megan: We’ve already seen Chuck interact with Bart on Gossip Girl, but will we see Lily find out he isn’t dead?
Yes, and you should start preparing for some major awkwardness! When we asked if Bart, Rufus and Lily will all be in the same room in the finale, Kelly Rutherford teases, “Yeah, that’s possible. I think that’s a definite possibility.” So yes people, the fact that Lily is kind of married to two people right now will be addressed. “You think that might come up,” Kelly says with a laugh. “What are we going to do with that?!” Hey, if anyone can handle two husbands it’s Lily Van Der Wooden-Bass-Humphrey.

As it picked up five new drama series, the CW also has renewed its strongest bubble series, Gossip Girl, Nikita and Hart of Dixie. It will be the final season for Gossip, third for Nikita and second for Dixie. The pickups of Dixie and Nikita are for 22 episodes, Gossip‘s is for an 11-episode final season.

Meanwhile, as expected, low-rated freshmen Ringer and The Secret Circle are not coming back. Here what the three renewed series had going for them. Gossip Girl is a big DVR gainer and has been a signature show for the CW that could go well together with Carrie Diaries, Hart Of Dixie has been very strong in online viewing, and Nikita is a big international seller for the CW’s sister studio Warner Bros TV.
