Dr. Zoe Hart is on a mission! New mom Rachel Bilson made a rare appearance two months after welcoming daughter Briar Rose while running errands in Beverly Hills on Tuesday, Jan. 13.

Bilson, 33, covered up her slim post-baby body in gray sweatpants and an oversized sleeveless black vest. She donned sunglasses, kept her dark locks up, and went makeup-free. According to Daily Mail, Bilson and boyfriend Hayden Christensen were reportedly getting Briar Rose's first passport at the time.

Us broke news in early November that Bilson and Christensen, also 33, welcomed their first child on Oct. 29. They named their tot after the 1959 Disney classic Sleeping Beauty; the three fairies call Princess Aurora Briar Rose while she's still under Maleficent's curse. After giving birth, Bilson stepped out for the first time in L.A. on Nov. 24.

The O.C. alum luckily has more free time since her CW show Hart of Dixie wrapped in October. In the season four premiere, it was revealed that (spoiler!) Bilson's pregnancy would be written into the show. As for whether the residents of Blue Bell will be returning for another season?

"No decision has been made regarding the future of Hart Of Dixie," a CW rep recently told TV.com. "So any discussion or reporting of whether or not the show will continue beyond the upcoming season is premature."
