Gwen Stefani, Denise Richards and others tell Us Weekly what they stash in their purse
The Bag: L.A.M.B. Aarika satchel
The Essentials: Almonds for snacking, action figures for sons Kingston and Zuma and her band's No Doubt's latest tunes. "My favorite part [about recording] is getting the demo CD at the end of a session and blasting it in my car," Stefani says. "I love to listen to it. I'm the only one still using CDs and everyone is panicked I'll lose one. I've been lucky so far, though!"
