As we know by now, Brittany Snow will star as a younger Lily van der Woodsen (formerly Lily Rhodes) in flashbacks on the May 11 episode of Gossip Girl.

The flashback sequences will set the stage for a Gossip Girl spinoff pilot, which will follow Lily's adventures in Los Angeles as a rebellious teenager.

If feedback is good, the new show will likely be picked up for the fall season.

Andrew McCarthy plays her father, Rick. Here's them on the set this week:
