Blake Lively is Having Brad Pitt's Baby

Blake Lively is on the set of Gossip Girl currently shooting in New York City on Thursday.

At a press conference last month, the Gossip Girl stars were asked who they were dating in their off-screen lives. Blake had some fun with reporters at a press conference over the weekend. “I’m having Brad Pitt‘s baby,” joked 20-year-old Blake.

Blake is currently working with Michelle Trachtenberg, Gossip Girl’s new “Queen of Mean.”
