Dax Shepard and Kristen Bell are the proud parents of a baby girl.
Shepard, 38, announced the news via Twitter this afternoon. "Lincoln Bell Shepard is here. She has mom's beauty and dad's obsession with breasts. Hooray!!!" he wrote.
Bell chimed in on her own Twitter page with, "My new roommate poops her pants and doesn't pay rent … basically Dax pre-sobriety. Welcome baby Lincoln."
The "Hit and Run" co-stars announced that they were expecting last November.
They've been engaged since 2009 but aren't rushing to get married as long as their lesbian and gay friends can't.
The 32-year-old "Veronica Mars" star told the Advocate last year, "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."
