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.
