Blake Lively: "I'm Having Brad Pitt's Baby!"

Starring on a show titled Gossip Girl appears to have given cast members Blake Lively and Chace Crawford a sense of humor when it comes to rumors about their respective love lives.

When asked who they were dating in their off-screen lives, the pair of kidders had some fun with reporters at a press conference over the weekend. "I'm having Brad Pitt's baby," joked 20-year-old Blake.

Meanwhile, co-star Chace, who has been seeing singer Carrie Underwood since the fall, risked starting a whole different kind of rumor when he answered, "I'm dating a gay, Jewish monkey."

We doubt that Angelina Jolie, who actually is pregnant with Brad's child, has anything to worry about from the blonde actress.

Calls to the monkey's rep about Chace's comment have not yet been returned.
