Rachel Bilson and on-again boyfriend Hayden Christensen hit the beaches in Barbados Friday.

The O.C. beauty and the Star Wars hero made a dash for the islands right after attending opening night for the Tribeca Film Festival.

The formerly-engaged couple had a lengthy split but we've been seeing them back together since the beginning of the year.

The Barbados jaunt may have been a belated birthday present for Hayden.  He turned 30 on April 19.
