Nicole Richie Pops into Petco

Nicole Richie shows off her growing baby bump on Tuesday as she shops for a new pet at Petco in West Hollywood.The mom-to-be picked up a pet goldfish, wrapping paper, fish stuffed animals and paper plates.

Along for the ride was Teen Vogue employee BFF Carlos Lopez (you may have seen him in a recent episode of The Hills while Lauren Conrad was at work for the mag).

Nicole also recently stubbed out rumors that she’s been smoking during her pregnancy.

“It’s really very sad and hurtful that journalists don’t believe in checking facts before writing false and unsubstantiated stories about my health and my pregnancy,” Nicole wrote in a statement released to Access Hollywood. “The healthy birth of my child is my number one priority.”

Nicole, 26, is due sometime in January with her and boyfriend Joel Madden‘s first child.
