Kristen Bell and Dax Shepard are expecting their first child

Congratulations are in order for Kristen Bell and Dax Shepard: Sources close to the couple have confirmed that they're expecting their first child in the spring.

"They're so excited -- they're both ecstatic. They can't wait to become parents," a friend tells People. "Kristen had a little bit of morning sickness early on but she just started shooting the second season of 'House of Lies' and is feeling great now."

This shouldn't come as much of a surprise, as Bell told Larry King back in August that having kids before marriage "really doesn't bother us." After all, Shepard and Bell could have a while to wait if they wanted to hold off on children until after they tie the knot. Though the couple has been engaged for nearly three years, they have said they aren't going to actually get married until same-sex marriage is legal in California.
