Dax Shepard and Kristen Bell.
Actress Kristen Bell and actor Dax Shepard are the parents of a new baby girl, the "Parenthood" star announced on Twitter Thursday.
"Lincoln Bell Shepard is here. She has mom's beauty and dad's obsession with breasts. Hooray!!!" Shepard tweeted.
This is the first child for the couple who co-starred in 2010's "When in Rome." The couple got engaged in 2009 and had said they were waiting until gay marriage was legal in California before they would marry. But Shepard, 38, did refer to Bell, 32, as his wife in a blog post about his dying father that went viral last week.
