Orange soda and sandwiches seem to be pregnant Rachel Bilson's choice of pregnancy cravings! The expectant O.C. alum was spotted indulging in the snacks at Cuz Fish Shack in Barbados while on vacation with her longtime boyfriend Hayden Christensen on Sunday, June 1.

Us Weekly exclusively announced just last month the couple of seven years are expecting. Bilson, 32, who has been relaxing on the island with her beau for the past week, kept it casual in a white tank top and tribal print shorts as she ate a sandwich and sipped orange soda.

Christensen similarly opted for a casual beach-side look. The Star Wars actor, who also sipped on soda, wore pink swim trunks, a grey T-shirt and a fedora hat. The 33-year-old was later spotted taking a sailboat lesson.

Earlier in the week, Bilson's growing bump was clearly visible in a black bikini as she soaked up the island sun and took a dip in the ocean.

"They've both talked about this for awhile and are so excited," a Bilson insider tells Us of the duo's soon-to-be family. "Everyone is beyond thrilled for them."
