Rachel Bilson was back at the beach in Barbados yesterday to continue her sunny vacation with boyfriend Hayden Christensen. Rachel was in her bikini on Friday and Saturday, too, swimming in the ocean with Hayden and exploring the area with other pals. She and Hayden took off from their home base in LA last week in order to first make a quick stop in NYC, where Rachel chatted up her Karl Lagerfeld-directed Magnum ice cream ad during the Tribeca Film Festival. She did the red carpet at her premiere last Thursday, but also made time for other media stops with Fox and Friends and FabSugar! Rachel shared with Fab all about working with an icon like Karl and giving us a preview of her character in the upcoming show Hart of Dixie.
