Rachel Bilson seems to be enjoying her pregnancy as the mom-to-be has been happily flaunting her bare baby bump in tiny bikinis.

According to E! News, the pint size actress was spotted out with her boyfriend Hayden Christensen enjoying a babymoon in Barbados.

On Sunday, the pretty brunette was seen wearing another black bikini that was pretty tiny, as she flaunted her growing belly.

Meanwhile, Rachel Bilson's beau wore a pair of swim trunks as the two fidgeted with their snorkeling gear as they made their way into the water.

This is the third time that the "Hart of Dixie" starlet has been photographed flaunting her baby bump in a bikini while on vacation with her man.

The couple headed to Barbados just days after news broke that Bilson is indeed pregnant and that she and Christensen are expecting their first child together after dating for seven years.

In the midst of her tropical getaway the starlet seemed to have developed a pregnancy craving for certain foods. Rachel Bilson was snapped eating what appeared to be a fish sandwich from Cuz's Fish Shack in Bridgetown.

Prior to her baby news the star told Health Magazine, "To start a family would be good, any year in the next few years," adding, "I've always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house."

Gushing about her boyfriend Hayden Christensen in the interview she revealed, "He's so incredibly supportive and considerate," adding, "It's so basic-that should be there. Because these things are so much more important when you're older.

"I've been in my relationship for seven years, so we've grown up together in a way. This is my partner, my support, just there for me no matter what. And vice versa."
