Kristen Bell met up with a friend to take their dogs for a walk around Los Feliz, CA, yesterday. Kristen's baby bump was visible through her plaid shirt — news that she's expecting came out yesterday! The baby will be Kristen and her fiancé Dax Shepard's first. They may be gearing up for their growing family, but the couple is also focused on work. The second season of Kristen's House of Lies premieres on Showtime in January and Dax is currently in the middle of filming his small-screen hit, Parenthood. He stopped by The Tonight Show last night to promote the NBC series. Dax talked about becoming a father and also added that his "mom is probably the most excited" about the news.
