Something must be done.

Mariah Carey’s ex-husband Tommy Mottola urges his former flame to surround herself with better management following the disastrous New Year’s Eve performance.

While Mariah sorts out her feelings following the debacle seen round the world and figures out who next to blame, Mottola, who helped launch Mariah’s career in 1990 with “Vision of Love,” has penned an open-letter for the elusive chanteuse to mull over.

“MC is arguably the greatest pop voice to come along in the last three decades,” he tells Page Six. “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.”

This is where it gets juicy.

“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!!” Mottola wrote, adding, “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!”

But there’s still hope.

“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.”

Mottola and Mariah wed in 1993, but divorced in 1998.

Mariah’s manager, Stella Bulochnikov, caught wind of the note and, in typical form, quipped back: “Really? Tommy is a relic. Did he give you that statement from a rotary phone?”

How professional of her! Between her mess of a team, the blame game aimed at **** Clark Productions, firing creative director Anthony Burrell and adding Mariah as a “special guest” on tour with Lionel Richie, something or someone needs to save Mimi’s career. 2017 and beyond needs her!
