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, and she arrives an hour late for her show in Luxembourg. As former employees leak information about Stella to the press, Stella must re-assess her strategy with the team to protect Mariah‟s reputation. Meanwhile, Mariah‟s hairstylist makes a costly mistake, and Stella must reluctantly bring back the fiery Danielle, Mariah‟s former hairdresser who comes with unsettled drama.

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.

As the European leg of the world tour concludes, emotions peak, and Mariah is relieved to find out her backup singer and best friend MaryAnne finally has forgiven Anthony, her co-creative director. Meanwhile, Mariah begins to recognize that her feelings for Tanaka transcend friendship. During a fun night out in Amsterdam, one of the dancers tries the local specialty for the first time and gets extremely high, and Mariah can't resist the urge to prank him with a big surprise when he wakes up in his bed.

In the season finale, as The Sweet Sweet Fantasy Tour comes to an end in South Africa, it's bittersweet for Mariah to say goodbye to her road family. Meanwhile, Tanaka is on top of the world when Mariah promotes him to Co-Director, but tension grows thick when Anthony is the last to know... When Mariah's upcoming wedding plans fall apart, she decides to take a leap of faith and follow her heart regardless of what outside opinion could be.
