Mariah Carey has certainly got into the festive spirit by declaring it's Christmas as she posts a video to her fans on Twitter.
In the black and white clip shared to her 21,850,151 followers the pop superstar is seen dressed in leather, while peddling an exercise bike and wearing a witches hat.
Moments later she lets out a spooky scream before she's heard saying: "It's time!" and this time she is dressed in a red and white fluffy jumpsuit and sitting on top of a reindeer.
