Oooooh, James Packer isn't gonna like this!

In a new clip from her reality show Mariah's World, Mariah Carey seems to have an admirer, back-up dancer back-up dancer Bryan Tanaka, whom you may remember as the pretty young thing she's been spotted hanging out with ever since her nasty split with Packer.

Could the businessman have seen the writing on the wall and pulled the plug before (or maybe after?!) his lady love got frisky with the dancer? It all looks a bit suspicious if you ask us!

We gotta say -- it's pretty weird to see the songstress planning for a wedding that we know isn't ever going to happen!

Watch the doomed diva when Mariah's World premieres on E! on December 4 at 9 pm!
