At just 22 years of age, Ariana Grande has already earned herself a reputation as a total diva, and now the showbiz world has united to berate what E! host Catt Sadler called her “spoilt brat behaviour” following an ugly incident at a cafe. The pint-sized popstar was caught on camera secretly licking doughnuts on a counter display. While fans may pay a premium for Grande’s pre-licked produce the majority of the population are disgusted by her actions. After initially trying to justify the incident as a protest against junk food, Ariana has since apologised on video, saying she made a mistake and seeing herself on film was a “rude awakening”. As rude as tonguing other people’s food?
