It's Mariah Carey's world -- and we're just living in it!

The singer released a promo for her upcoming E! reality show, Mariah's World and it's clear she's all the diva we think she is!

In the promo, Mimi, who is dressed in sequin lingerie, says while reclining on top of a couch , "I'd rather, like, make everything fun." She adds, "Is this a normal outfit for people to wear? I don't know, but I'm at home and this is what I wear."

Viewers are shown the hitmaker's super glam life as a mom and superstar, as well as the road to her Vegas residency and her upcoming wedding to billionaire fiancé James Packer.

In the clip, Mariah also makes some pretty intense (and possibly not so serious) demands for her nuptials. At one point, the bride is on the phone with presumably a wedding planner and demands "white tigers" and "albino elephants" for the wedding. Luckily it's a joke -- but we love that the wedding planner thinks she's being serious!

Mariah's World premieres on E! on December 4 at 9 pm! Click here to watch the promo!
