Rachel BilsonRachel Bilson is flaunting her bikini body on the beaches of Barbados with her on-again, off-again boyfriend and former fiancee, Hayden Christensen.

Bilson was in New York at the end of last week for the Tribeca Film Festival, but quickly hopped a flight to join her birthday boy boyfriend.

The pair were spotted over the weekend getting some R&R together, and we can't help but assume that these two are back together.

Reports first surfaced back in June of last year that the pair had separated, and they officially announced their split two months later. After some time apart, the couple looked to be dating again in November of last year, and although there has been no official confirmation, a romantic beach getaway can pretty much speak for itself.
