Apparently Ariana Grande is such a diva that even her life coach can't deal with her. Grande's life coach reportedly quit amid recent reports of her impossible attitude. The 21-year old has been dealing with damaging rumors lately that her antics are too much for others to handle.

“He just couldn’t take it anymore,” an insider tells New York Post’s Page Six about Grande’s unnamed life coach. He was in charge of keeping her healthy, but walked away from the job due to her attitude. “Everything people are saying about her is true.”

Reports emerged last week that the 21-year-old singer scorned fans behind their backs after a radio show in New York over the summer. “She did autographs and pics and was all smiles until she got into the elevator,” a source tells Daily News gossip column Confidenti@l. “And as soon as the doors shut she said, ‘I hope they all f—king die.’ ”

This is not the first time Grande, who is managed by Justin Bieber’s mentor Scooter Braun, has been accused of diva antics. Television personality Giuliana Rancic also said Grande has earned herself a “difficult” reputation. “I think she does have a little bit of a diva thing going on,” she told E!, before recounting a meeting with Grande at last year’s AMAs.

“I remember, I think it was at the AMAs, she came up on the platform, and normally I stand on this side [her left side] to the camera," Rancic said. "I had to fight 13 years to get this side to the camera, it's my good side, but I fought 13 years for this, OK? Little Ariana comes over, I feel like 'bing,' elbow in my side, I'm like, ‘What's going on?’ and they push me to the other side.”

Grande’s camp is said to have told journalists to shoot her only from the left side of her face.

“So I had to be on my ugly side. ... But when you're new on the block, when you're trying to earn your stripes, you're young, you just gotta do what you gotta do, try to get a great reputation, try to go overboard to please people,” Rancic said.
