Rachel Bilson Bares Her Bikini Bod

Rachel Bilson hits the beach in a maroon bikini as she relaxes on vacation with beau Hayden Christensen on Sunday (April 24) in Barbados.

The 29-year-old actress and Hayden, who just turned 30, have been spending time on the beach together since Friday.

Earlier in the week, Rachel wore Chanel Haute Couture as she premiered her new series of short films with Karl Lagerfeld at the Tribeca Film Festival!

The short films are for Magnum Ice Cream and feature Rachel as an art student, a ballerina and a model.

FYI: Rachel is wearing a Tara Matthews bikini and an A.L.C. classic gray pocket tee.
