Bilson's bumpin' bikini bod! Now that the cat's out of the bag, Rachel Bilson is letting her growing baby bump hang out for the world to see. After Us Weekly exclusively broke the news of the Hart of Dixie star's first pregnancy, Bilson and longtime boyfriend Hayden Christensen traveled to Barbados for a beach-side getaway. 

The couple was first spotted on Thursday, May 22, when the O.C. alum, 32, sported a black, scalloped bikini while splashing in the waves. Then on Monday, May 26 they were out and about again, tanning on the shore, hitting the waves in an inflatable boat with a friend, and even taking a seat on a motorized boat to explore the island. 

Bilson wore yet another two-piece, leaving her blossoming bump out as her doting boyfriend stayed close by. 

The couple's first pregnancy was a longtime coming. Hart of Dixie costar Jaime King recently dished to Us about her pal's impending motherhood, saying, "I knew she wanted a baby, she wanted it so badly. She's going to be in such good hands—she's in a really good space. I'm really thrilled for her."
