And they’re off! Rachel Bilson and her newborn daughter Briar Rose are joining dad Hayden Christensen on the road. The couple, who welcomed Briar, their first child, back in October, are traveling to Atlanta where the Star Wars actor will be filming 90 Minutes in Heaven, a source tells Us Weekly.

The couple chose to travel from Los Angeles to Atlanta via RV, the source explains, in order to avoid the airport.

“Rachel thinks it's a little over the top but she's going along with it,” the source adds of the decision to drive cross country.

The new mom was spotted stocking up on snacks in Los Angeles on Thursday, Jan. 15. Wearing a comfy white long-sleeved shirt and baggy gray sweats, the Hart of Dixie star looked relaxed to be boarding the boatload of a vehicle, which Christensen appears to be driving himself. 

While chatting with Us Weekly at the Showtime premiere party on Jan. 5, Bilson’s costar Mircea Monroe told Us Rachel’s “doing great” post welcoming her mini-me.

“She’s incredible,” Monroe said. “She’s a great mom.”
