Kristen Bell and Dax Shephard have given birth to a baby girl.

The couple - who got engaged in 2009 - announced on Twitter yesterday they have welcomed Lincoln Bell Shephard - their first child together - into the world. Dax, 38, wrote to his followers, "Lincoln Bell Shepard is here. She has mom's beauty and dad's obsession with breasts. Hooray!"

The new mother was nervous towards the end of her pregnancy, and admitted she was relying on the help of friends who had already made the leap to parenthood. Kristen, 32, had recently said, "I'm gathering advice from everyone. I have a lot of friends with kids and work with a lot of people with children, so I'm just asking what's their best bit of advice. The nice thing is that, hands down, every person I know that has ever had a kid has looked at me with confidence and said, 'Oh, this is the best thing you'll ever do with your entire life.' So, that's nice to know."
