However, there are rumors, and later was confirmed by daytime talk show host Wendy Williams in Star Magazine , that the new coach Usher acting like a diva.

While Shakira would be expected to behave like a diva since she is the only female among four coaches, it doesn't seem to be the case in season 4 of "The Voice."

Wendy Williams reported that Usher shows up late for the show and wants to "be catered to like he's the top dog on the show." Auditions can detect some tension between fellow judge Adam Levine and Usher as he showed kindness to everyone in the show except Usher.

Besides, William stated that a Chinese billionaire was going to pay Usher $1 million to have him perform at a birthday party. But probably due to his ridiculous request to have a private plane for his crew, the billionaire has turned to fellow "The Voice" coach Adam Levine.

However, it seems NBC shows little concern for the rumors as long as the ratings continue to grow. "The Voice" just recently got a strong rating of 4.9 among adults and more than 13 million viewers on one episode, Entertainment Weekly reported.

Of course there is nothing confirmed in the Usher rumors and it is still up the auditions to judge who would be most likely to be a diva of "The Voice."
