Rachel Bilson went 'glamping' with Hayden Christensen for her 33rd birthday.

The couple, who spent a month-long babymoon in Barbados earlier this summer, were spotted dressed in casual clothing, including overalls and baseball caps, as they stocked up on sweet treats for their adventure, according to UsMagazine.com.

The duo, who have been together for seven years, can't wait to become parents.

A source previously said: "They've both talked about this for awhile and are so excited."

The brunette beauty's co-star Jaime King, who has a 10-month-old son, James, also predicted Rachel will be an amazing mother.

She said: "Her best friend has a kid and she has a lot of friends with children, so I'm just there to support her however I can and honour and respect her processes.

"She loves James, she's always bringing him toys. Just seeing her with my son, I know she's going to be the best mother."

Rachel admitted last year she was keen to start a family with the 'Star Wars' actor.

She said: "I definitely have family on the brain. Having kids is something I want to see in my future - I hope."

Rachel and Hayden, 33, met in 2007 on the set of 'Jumper' and got engaged a year later.

However, they called off their engagement in August 2010, but reconciled three months later.
