Nicole Richie and Ashlee Simpson go shopping together at Barney’s Beverly Hills on Thursday.

Ashlee, 23, will be making an in-store appearance at the Zellers store at Square One, in Mississauga, Canada, on Saturday Aug. 23 for the relaunch of the Request clothing line. Simpson was chosen for the advertising due of her “hip” persona which reflects the brand’s personality, said Geoff Hardwicke, Zellers director of marketing.

Nicole, 26, is now launching a Web site for the charity that she and boyfriend Joel Madden started - the Richie Madden Children’s Foundation.

“The Web site will be a registry, like for a bridal or shower registry, where low-income women list things they need for their babies,” the source said. “More well-off people will then go on and buy stuff for the children,” a source told the NY Daily News.

“She was a cheerleader,” says Nicole of her character, Heather. “Kind of that b—-y mean girl.”

Looks like old habits die hard.

“I had a stunt double,” added Nicole on her action-packed role as a girl girl on NBC’s Chuck. “But they said I was allowed to do as much as I wanted–except for serious things.”

Nicole Richie just confirmed that her 2005 coming-of-age novel, The Truth About Diamonds, is being transformed into a TV show. The former Simple Life is even going to be part of the production, natch.

“I would definitely produce and definitely be in the show,” the socialite tells E! “[But] I don’t know if I need to be the star of this show. I’ve got a lot going on right now.”

The Truth About Diamonds is about this girl named Chloe Parker. She’s a club kid with a drug problem but manages to get her own series of “reality commercials” with her friend Simone. The book tells about Chloe’s struggle with fame, drugs, and romance.
