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.

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.

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.

Festive Mariah makes special memories for her kids and opens up about her past.

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.

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.

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.

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.
