Sharon Osbourne doesn’t always chew up singers and spit them out. She can sometimes be nice. The “America’s Got Talent” judge and husband Ozzy caught Eden Espinosa‘s cabaret show, “From Eden With Love,” at Feinstein’s. The Os bournes — in town while Sharon films “Ce lebrity Apprentice” — turned up unannounced and mixed with other audience members, even cramming into a booth with strangers to get a better view. Said one spy, “At the end of the show, the Osbournes sent Eden a bottle of champagne. It was a real seal of ap pro val from a rock god and goddess.”
