Kristen Bell's family continues to grow! The House of Lies star, 33, is pregnant again and expecting her second child with husband Dax Shepard, a rep for the couple tells Entertainment Tonight. The Hit and Run costars are already parents to daughter Lincoln, nearly 15 months.

"I can confirm that Kristen and Dax are expecting their second child and a sibling for Lincoln," the rep says. "The whole family is beyond excited."

Married since last October, the Veronica Mars actress and the Parenthood star welcomed their first child in March 2013. Speaking about her baby daughter with Us Weekly last August, Bell gushed, "I love [motherhood]! She's absolutely intoxicating."

More recently, at the Amex Everyday Event in New York City this past April, she told Us, "I want to be very hands on. I want to cook for my family and feel present for them. I'm always missing her when I'm not there."

Shepard, 39, is pretty smitten, too. "It's like he's just made a new best friend," the Frozen actress joked to Ellen DeGeneres just a few weeks after Lincoln's birth. "He just talks to her all the time and sings to her all day. It's wonderful."
