'Mariah's World' Trailer: Backup Dancer's Huge 'Crush' On Carey Confirmed!

Oh snap! Mariah Carey's budding relationship with backup dancer Bryan Tanaka has been well documented thanks to her upcoming docuseries, Mariah's World.

As RadarOnline.com readers know, romance rumors quickly began swirling after Carey split from fiancé James Packer in late October.

Before her big breakup, there was buzz that the Aussie billionaire became extremely "jealous" of Tanaka, whom Carey had grown close to during the relationship meltdown.

Packer reportedly became so enraged that he used some of his close connections to get Tanaka banned from entering Caesar's Palace so that he couldn't be any where near Carey while she performed. But his plan clearly backfired.

"Tanaka does have a crush on her," a staffer on Carey's team says in the trailer, to which another team member replies, "What are we going to do with him?"

"You saw it — he's not leaving that easily," the first staffer warns.

So far, Tanaka hasn't left at all! The pair has been spotted on numerous dates together in the last few weeks, with Tanaka even spending a night in Disneyland with Mariah's twin children, Monroe and Moroccan, whom she had with ex-husband Nick Cannon.

But is Mariah really moving on that quickly? According to a source very close to Carey: "She is in self-destruct mode right now and she has been for several months. She is picking up some of her old bad habits and the people around her are starting to worry for her well-being."
