Stepping out for a social call, Rachel Bilson and Hayden Christensen attended a friend’s birthday party in Los Angeles on Saturday (June 21).

The preggers “Hart of Dixie” dame covered up her baby bump in a beautiful flowing dress as she accompanied her handsome fiancé into the shindig.

Rachel told Health magazine that motherhood is an exciting adventure and she can’t wait to get things underway.

“I’ve always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house… [And Hayden has been] incredibly supportive and considerate.”
