Rachel Bilson is one pregnant lady! Looking like she's about to pop, the Hart of DIxie star was out and about in Hollywood on Monday. The 33-year-old grabbed a cold drink to escape the unprecedented Los Angeles heat -- and she looked so stylish doing it!

For the afternoon excursion, the petite brunette wore a floaty bohemian maternity dress and paired it with flip flops and a pricey Chanel bag. Too cute!

The former O.C. star announced in May that she and longtime boyfriend, Star Wars actor Hayden Christensen, were expecting their first child.

In August, Rachel had a baby shower in which famous friends Natalie Portman (who starred with Hayden in the Star Wars) and Jaime King attended. The mom to be was surrounded by her friends and family to celebrate the impending birth of her wee one.

A source told Us Weekly that at the party, "Instead of gifts, everyone brought a birth bead. Each person gave her a piece of advice and a blessing along with the bead ... She will use the beads for strength during labour."

We hope she has those beads on her -- it looks like she could give birth any second!
