Who is Kaylee DeFer? She's the latest schemer to head to the Upper East Side and join Gossip Girl.
The pretty young star of the Fox comedy The War at Home and the WB drama The Mountain will join the cast of Gossip Girl as a recurring character; her first appearance will happen sometime in 2011.
No word yet on whom she'll play, but judging from her looks and the way the season has shaped up, we're guessing she's a love interest for Dan Humphrey, or another Queen Bee trying to bring Serena down, or maybe someone for Chuck. We'll just have to wait and see!
