Celebrity couple Dax Shepard and Kristen Bell welcomed a baby girl on Thursday.  They gave her a unique first name ... Lincoln.

The 'Parenthood' actor, 38, tweeted, "Lincoln Bell Shepard is here.  She has mom's beauty and dad's obsession with breasts.  Hooray!!!"

Bell is a first time mom and co-stars on Showtime's 'House of Lies' with Don Cheadle.

During an interview last year, the actress explained that she and her fiance haven't tied the knot because they are unhappy about the current state of marriage inequality.

She said, "The reason we're not rushing to get married is because I don't feel appropriate taking advantage of a right that's denied to my gay and lesbian friends.  That's why we've been so hesitant.  Dax and I have talked about it a lot, and this issue is very important to both of us.  We're just standing up for what we believe in. Period."

Besides her current television gig, she'll soon be reprising her role as lead character Veronica Mars in the film version of the 2004-2007 series 'Veronica Mars.'
