Actress Kristen Bell is expecting her first child with her fiance Dax Shepard.

A representative for Bell has confirmed the happy news to Usmagazine.com.

The couple got engaged in 2009, after dating for two years.

Earlier this year, Kristen and Dax revealed they were planning to start a family, but have previously said they don't want to walk down the aisle until gay marriage was legal in the state of California, where they live.

In February, Kristen, 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.''
