Since the premiere episode March 25th, Season 4 of The Voice has experienced the highest ratings in the show's history. Many are attributing the ratings spike to the chemistry between Adam Levine, Blake Shelton, and the two new judges Shakira and Usher, however rumors are starting to circulate that there is some diva drama behind the scenes. Who's the diva? You'll be surprised to find out it's not Shakira, the show's only female host-it's Usher!

First reported on the Wendy Williams show, it seems the diva antics began when a Chinese billionaire approached Usher. The businessman offered Usher $1 million to perform at his son's birthday party in New York City, but Usher ultimately rejected the offer because his long list of outrageous demands weren't met. Some of these demands included having his entire entourage, a large group of people allegedly comprised of assistants, dancers, backup singers, hair dressers, personal trainers, friends and family, flown in by private jet plane and then put up in penthouse suites. After Usher turned down the offer, the businessman approached his The Voice colleague Adam Levine with the idea and he accepted.

In addition to this awkward conflict with Adam Levine, crew members of The Voice claim that Usher constantly arrives late and demands that he be treated like top dog. Sure, Usher seems like a sweetheart in The Voice judge chair, but he may just be a sour sweet-talker when the cameras are off. The Voice better keep receiving high ratings if Usher plans to continue acting this way...
