Who’s Gossip Girl’s Newest Leading Lady?

When Gossip Girl returns from its winter hiatus, there will be a new leading lady on the Upper East Side. Up-and-coming actress Kaylee DeFer has been added to the roster, and with previous roles that include “Beautiful Girl” on How I Met Your Mother and “Cute Girl” on Drake & Josh, it’s safe to assume that she’ll play a love interest for Dan. Or Chuck. Or Nate. Or, most likely, all three, since they’re into that kind of thing.
