Mariah Carey headlined the world's Christmas extravagant which was streaming live on November 17. The R&B diva performed in five European cities, Poland, Montenegro, Croatia, Germany and Macedonia, at once by appearing via hologram.
The mother of two catered the crowd gathering in front of a Christmas gift-shaped stage by singing "Oh Santa", "Hero", "Silent Night", and "All I Want for Christmas Is You". Just before the gig was kicked off she tweeted, "MC's ready! Are you? MC's Christmas gift is about to unwrap!"
Beside singing at the special concert, Mariah also prepares a new music video as a gift for her fans. It's a clip to support a "When Christmas Comes" remix which features John Legend. Additionally, she will appear in Justin Bieber's clip to promote his re-recorded version of "All I Want for Christmas Is You".
