Mariah, 54, who makes millions each year from the song, is fronting the Victoria’s Secrets festive campaign.
Its video sees her entombed in a block of ice while a clock ticks down from 11.59pm on October 31. The star traditionally “thaws” herself each year on November 1 for the season.
And in the ad, Halloween characters, including Ghostface from Scream, use hairdryers to free her.
As they succeed, Mariah sings “It’s time!”, prompting the ice to crack. She emerges while her multiple chart-topping anthem plays. She has picked and modelled her favourite undies from the collection, including corsets and camisoles.
All I Want For Christmas Is You was first released in 1994 but was held off the No1 slot by East 17’s Stay Another Day. Mariah, who claims she started writing it on a Casio keyboard, finally hit the top of the UK chart with it just before Christmas 2020.
