Nicole Richie & Cameron Diaz Have a Fun Family Day with Sparrow & Harlow!

Nicole Richie and her sister-in-law Cameron Diaz leave the nail salon with Nicole‘s eight-year-old daughter Harlow (not pictured) on Saturday (July 30) in Beverly Hills.

That same day, Nicole, 34, and Cameron, 43, were joined by Nicole‘s spouse Joel Madden as they took Harlow and her brother Sparrow, 6, to a party at Duff’s Cakemix, an interactive bakery in Los Angeles.

It was recently announced that Nicole will be replacing Kimrie Lewis-Davis in the NBC series Great News.

“I’m very excited,” Nicole told W magazine on Thursday. “I just found out two days ago. I’m in New York, not home, so it’s kind of a surreal feeling, I can’t wait to go home and celebrate with my family.”
