Mariah's World

Mariah plans her upcoming nuptials to billionaire James Packer and the launch of her first world tour in a decade simultaneously, which presents a difficult dilemma. Meanwhile, Mariah must race the clock to showtime and entrust the tour at the hands of her new tough manager, Stella.

As Mariah continues on a grueling tour schedule, she does all she can to be the best mother to her twins and establishes a comfortable home base in London. But when a heated disagreement erupts between key performers, Mariah is pulled into the middle of their conflict and torn between two of her closest friends.

Mariah must win back her audience when a time zone change goes unnoticed; former employees leak information about Stella to the press; Mariah's hairstylist makes a costly mistake; Stella must bring back Danielle, Mariah's former hairdresser.

Festive Mariah makes special memories for her kids and opens up about her past. Molly continues to jump through hoops to please her tough boss, Stella, but when she disappears in Stella's time of need, tears are the least of her worries. Meanwhile, Tanaka lights a match with MC when he jumps out of her anniversary cake.

Mariah spends more quality time with her road family when she rents a big house for everyone to stay in Lake Como, and Tanaka struggles to keep his feelings platonic within close quarters. But Tanaka's moment in the sun with Mimi may be in jeopardy when he suffers from an unexpected injury that could send him home.

The loss of a legendary friend, Prince, leaves Mariah devastated moments behind a Paris show. When another dancer gets injured, Mariah starts to feel it's time to simplify the show, but Anthony is against the idea and now he must train two new dancers quickly. When Mariah's fiancé James comes to visit, Tanaka is left heartbroken, realizing everything he was feeling was his fantasy.
