"Mariah's World" gives fans, viewers and "lambs" alike a peek into the life of the award-winning singer, songwriter and icon Mariah Carey. During the eight-part event, Mariah is faced with the overwhelming demands of her time as she launches her world tour, plans a wedding and is a loving doting mommy to her twins.

When Mariah isn't selling out world tours or taking diamond filled luxurious bubble baths, she is shaking things up in her professional life and has brought on Stella Bulochnikov, as her tough, new manager. Stella is determined to steer the ship and tighten things up, which leaves some of Mariah's large entourage consisting of a creative director, hair and makeup artists and dancers on edge. Part of Stella's quest to take Mariah's career to new heights includes her first world tour in over a decade.

In a group filled with strong personalities, conflicts arise and tensions build up leaving the diva herself on pins and needles. Mariah's personal life is filled with special moments with her babies, who always come first and have joined her for the tour. Between being a mommy and working hard to give her lambs her best on stage every night, she is also trying to find time to plan a wedding. Beyond the flashing lights and adoring fans, "Mariah's World" is a fantasy many wish was their reality.
