For its final season, Gossip Girl has landed a major real-life socialite: Alexa Chung. The 28-year-old model/TV host was spotted on the CW show's New York set yesterday, getting ready to film on location in the Lower East Side. 

Which character Chung will be playing has yet to be revealed, but she's a nice complement to an already sexy cast that includes perennial eye candy Blake Lively and Leighton Meester
