(Well, maybe.) The new show will focus on "Gossip Girl" mom Lily Van Der Woodsen, but there's a twist ...

EW.com reports the show will actually be a prequel. It's all about Lily's life as a teenager in the 1980s living in the valley. (Um, sound familiar??) The pilot will air on May 11, in place of a "Gossip Girl" episode.

What do you think -- gag me with a spoon or totally killer?
