Just in time for Christmas, Kristen Bell, 34, and Dax Sherpard, 39, have welcomed their second child together — a baby girl!

The 'Parenthood' star happily (and hilariously) announced the birth of his daughter on Twitter.

"Delta Bell Shepard is here," he wrote. "She doesn't look like either @IMKristenBell or me, but we're gonna keep her anyway. #christmascameearly."

What a sweet little name! It has such a cute ring to it.

Delta is the second daughter for the couple, who married in October of 2013. They are also parents to one-year-old Lincoln who they welcomed in March 2013.

"She's very interested in the shape of my belly," Kristen said of her first born while pregnant. "Very interested in offering it water and crackers and giving it smooches. She could just be mimicking what we're doing but I have a hunch she knows what's happening."

Congrats to their growing family!
