Rachel Bilson Debuts Baby Bump in Black Bikini in Barbados With Hayden Christensen

They jetted off for a babymoon in Barbados last week.

And it looks as though it was just what the doctor ordered, as Rachel Bilson and her beau Hayden Christensen stepped out again on their holiday looking rested and relaxed on Monday.

The couple, who confirmed this week that they are expecting their first child later this year, were first spotted soaking up the sun in Barbados on Thursday last week.
