E! has announced the new reality series starring singer and songwriter Mariah Carey will premiere Sunday, December 4 at 9PM ET/PT. The show will also debut on Bravo.

Subsequent episodes of Mariah's World will air on E! every Sunday night at 9PM ET/PT.

In Mariah's World, Carey is faced with the overwhelming demands of her time as she launches her "Sweet Sweet Fantasy" European concert tour, plans a wedding and fulfills her duties as mom to four-year-old twins Monroe and Morrocan, whom she had with her ex-husband Nick Cannon.

Carey is scheduled to make 28 performances on the tour and travel to destinations including the United Kingdom, Europe and Africa. And her personal life is tense at times because she hired a new no-nonsense manager, Stella Bulochnikov, who put some of the singer's creative team on edge. 

"In a group filled with strong personalities, conflicts arise and tensions build up leaving the diva herself on pins and needles," according to the network, but Carey's personal life is also "filled with special moments with her babies, who always come first and have joined her for the tour."

All of this -- and a wedding! (Although Carey and her fiance during filming, James Packer, recently split).

Carey previously served on American Idol's judging panel with Keith Urban, Nicki Minaj and Randy Jackson for Season 12 back in 2013.

Carey got engaged to Packer in January after Cannon filed for divorce from her in December 2014.

Mariah's World is being produced by Bunim/Murray productions in association with Magic Carpet Productions. Carey, Gil Goldschein, Jeff Jenkins, Farnaz Farjam and Stella Bulochnikov are serving as executive producers.
