Mariah Carey
It’s no surprise that Mariah Carey is a diva, but it could be forgivable if she gave something back to the peeps who wait on her! Mariah reportedly once kept a restaurant open much later than it’s normal closing time with a large party of friends…and left nothing in return. The New York Post reported: “Mariah and crew were very diva ish with their demands. Despite keeping staffers jumping and a high tab, no one left a tip.”
