Rachel Bilson sure seems proud of that baby bump.
The expectant actress, who is currently enjoying a babymoon in Barbados with beau Hayden Christensen, bared her growing belly in yet another black bikini while soaking up the sun on Sunday.
Bilson flaunted her baby bump in a tiny black two-piece while her man wore a pair of swim trunks as the two waded in the water with their snorkeling gear in hand.
This is the third time the mama-to-be has been snapped showing off her belly in a bikini while on vacation with Christensen. The two jetted off to Barbados just days after E! News confirmed that the Hart of Dixie star is expecting her first child with her boyfriend of seven years.
In addition to the duo's PDA-packed outings on the beach, Bilson gave us all a peek into her pregnancy cravings when she was snapped indulging in what appeared to be a fish sandwich from Cuz's Fish Shack in Bridgetown.
While the private couple has yet to comment on the baby news, the actress recently opened up about her desire to have children in the June issue of Health magazine.
"To start a family would be good, any year in the next few years," she divulged to the mag, which featured Bilson showing off her fit frame on the cover. "I've always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house."
The former O.C. star also gushed that her hunky man is "so incredibly supportive and considerate," proving he's bound to be a doting dad.
Bilson, 32 and Christensen, 33, met on the set of Jumper and began dating in 2007.
The two got engaged in December 2008 but called it off in August 2010, only to reconcile three months later.
