Sweet Charity

There's no doubt about it--with the recent smash single "Hollaback Girl," Gwen Stefani is at the top of her game in the music world. But that doesn't mean she won't make time for friends. In fact, on September 18, the pop diva brought hubby Gavin Rossdale to catch good friend Christina Applegate in the musical comedy hit Sweet Charity. After the standing ovations, Broadway.com caught up with the galpals backstage.
