Nicole Richie and Joel Madden brought 2-year-old Harlow and recently 1-year-old Sparrow to dinner at a California Pizza Kitchen in LA last night. Nicole sported another kimono from her own collection for the family night out, and this morning she was up for an early flight out of town. She's been on the road promoting her new novel, Priceless, which is just one of the recent celebrity book releases. She joked about singing at a signing on Wednesday, but one place she may not want a family performance is her upcoming wedding. While Joel would love for her dad, Lionel Richie, to play a song on their big day, Nicole jokingly shot down the idea.
