The actress was spotted in Ventura, Calif. Monday rocking a very comfortable new mom look. She wore Current/Elliott The Ranch Hand overalls with a green baseball cap with the letter "C" (for Christensen?) on it.

She paired it with a sleeveless white shirt and neon pink New Balance sneakers. She also carried a brown leather Alexander Wang handbag.

She also hung on to a plastic grocery bag filled with Coca-Cola and other sodas. Christensen was also with her. The OC star was also seen sporting another casual look when she rocked a white dress topped with navy blue embroidery along with black and brown Birkenstock thong sandals, and grey cardigan. She opted out of wearing makeup and pulled her hair in a high messy undo. She completed her look with a pair of red sunglasses she hooked on the top of her dress.

Christensen also looked comfy on their camping adventure as he wore grey jogging pants, a grey and striped shirt with a blue and grey hoodie. Check out the pictures over at Us Weekly.

Bilson's first pregnancy was announced in May.

An insider told Us Weekly, "They've both talked about this for awhile and are so excited."

Her Hart of Dixie co-star Jaime King also said she is happy for Bilson.

"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 honor and respect her processes," the mother of one told Us. "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."

She and Christensen have been dating for seven years.
