Pregnant Rachel Bilson Brings Out Her Bikini

Rachel Bilson put on a Beach Riot bikini last month for a relaxing day by the pool in Cancun. The pregnant actress spent the afternoon hanging out with her fiance Hayden Christensen and other friends poolside. There was no sign of a bump, but her exciting baby news was just revealed on Wednesday!

Although they switched their destination to Mexico, Rachel and Hayden continued their annual vacation tradition, as they took a trip together to Barbados in April last year as well, where they splashed around in the water and even snuck in a little PDA. They were in Barbados together in 2012, too. The couple's retreat was a celebratory one since it came just before Hayden's 33rd birthday and the third season finale of Rachel's TV show Hart of Dixie.
