Rachel Bilson's baby bump is becoming more apparent as the "Hart of Dixie" actress went out for some home improvement shopping last week in Los Angeles.

The 33-year-old actress was with her longtime partner Hayden Christensen as they decided on a few selections of rocks, the Daily Mail said.

"The OC" star stayed in her car while her 33-year-old "Star Wars" actor Hayden Christensen made his way to the collection of rocks and showed them to his girlfriend.

The 33-year-old actress looked calm and collected as she is in her nesting phase while her boyfriend did all the errand.

Rachel Bilson sat comfortably while sipping from a bottled water.

The actress was also seen in the past weeks as Rachel Bilson showed her baby bump when she went out for some retail therapy shopping.

She was spotted running errands in Hollywood with a casual leggings and loose grey top that covered her baby bump.

Meanwhile, the "Hart of Dixie" actress' close gal pal Jaime King has some words of advice for the mother-to-be.

"I tell her everything because she and I are very, very close. Rachel and my son have had a love affair from the very, very beginning since he first met her," Jaime King told E! News.

Jaime King also added that her close gal pal has "always been one of the most supportive people in my life in regards to my pregnancy."

"People forget that she's growing a human being inside. I had to get IV fluids because it was so hot when I was shooting in Burbank, but I never wanted that to happen to her. I was always super, super, super protective of her and her child," the 35-year-old actress said.
