He's got her back... sort of.

Mariah Carey's ex-husband Tommy Mottola just weighed in on the singer's disastrous NYE performance with an open letter, and the music executive basically places all the blame on her management team. He was also critical of his ex-wife's decision to film her reality show Mariah's World.

"MC is arguably the greatest pop voice to come along in the last three decades. She has had more number one hits than any pop artist in history!!! She is a global icon and a treasure with incredible talent not only as a singer but as a great songwriter. What happened on NYE could’ve happened to anyone! Yes, her technical people should’ve helped pay more attention to all of it so that there was no chance of that happening," he began.

"My only advice is that she should hire more seasoned and respected professionals to surround her and help her with her career! I would never have encouraged her or guided her to do something like a reality television show!!!!! I don’t get it!! That does absolutely nothing for her integrity, her credibility, or her massive talent!! She should take a step back, think carefully and figure out what to do next. That is what she does best.. most certainly none of these issues or problems ever existed with her in her early days at Sony for the first 10 years when she skyrocketed to global superstardom!! Where absolutely meticulous and methodical attention was paid to every single detail and nuance that went on into her career!” he continued.

"It could have happened to anyone and it has, so everyone should just get off her back and leave her the hell alone and hopefully she will find her way to the right professionals for guidance. It’s never about the fall, it’s all about the recovery," he concluded.

Mimi's manager Stella Bulochnikov clearly didn't appreciate the diss and promptly fired back. "Really? Tommy is a relic. Did he give you that statement from a rotary phone?” she sniped.

Despite admitting she was "mortified" over the incident, the "Sweet Fantasy" songstress isn't letting all the bad press get to her. The evidence? She posted the below photo of herself relaxing in a hot tub in Aspen. See, she's totally fine and not freaking out at all! Or at least she wants you to think so...
