The 33-year-old actress is currently pregnant with her first child with the actor, and the two were seen shopping at a home renovation store in Los Angeles on Wednesday.

Although former The OC actress Rachel stayed inside their car, Hayden got out and did his bit, selecting from a collection of rocks.

The Star Wars actor, also 33, carried the rocks back and forth to his star girlfriend, as she approved them from her car seat.

The father-to-be sported a blue Nirvana band t-shirt under a casual hoodie as he used his muscle power during the shopping trip.

Meanwhile, the stunning brunette sipped from a bottle of water as she directed him from the comfort of their vehicle.

As her due date draws closer, the expectant parents, who have been in an on/off relationship since 2007, are no doubt keen to make their home as perfect as possible for their new arrival.

It's thought the Hart of Dixie star is going to give birth before the end of the year.

Earlier in the week, she was seen out and about running errands in Hollywood, wearing a casual outfit of fitted black leggings and a flowing, grey top that covered her blossoming bump in the most flattering of ways.

It was recently revealed that the expecting mum was given birth beads by Natalie Portman and Jaime King at her baby shower on August 31. 

She was surrounded by her friends and family, including the Black Swan actress and her Hart of Dixie co-star, each of whom gave her a birth bead.

The beads were then strung together into a necklace for Rachel to wear while she is in labour, so as to give her strength.
