Mariah came on a suspended sleigh dressed in red dress similar to Vegas opening, singing All I Want For Christmas Is You Remix. Mariah took her first break after performing Make It Happen and came back on stage with Angels Cry. Before performing Subtle Invitation, Mariah asked for lipstick and says, "I'm a diva. They call me one so I'm gonna start acting as one." MC takes another break after It's Like That, Trey Lorenz does a solo with the Michael Jackson song Rock With You.
