Brittany Snow has reportedly signed on to star as the young Lily Van der Woodsen in the Gossip Girl spinoff. Of course, since Star magazine broke this story, we're still reserving judgment on whether it's true.
Snow is probably best known for her role as Amber Von Tussle in the movie Hairspray, as well as her starring role on the NBC series American Dreams.
If the rumors are true, Snow will join Krysten Ritter of Gilmore Girls, who has been cast as Lily's older sister. The Gossip Girl spinoff will focus on Lily's life in Los Angeles in the 1980s and is expected to air as an episode of Gossip Girl in May on The CW.
The character of (grown-up) Lily van der Woodsen is currently played by Kelly Rutherford on Gossip Girl. Snow does sort of resemble her. Might be a good choice!
