She's the most festive popstar of them all, but Mariah Carey's Christmas is getting off to a rocky start this year. 

The singer has been forced to cancel three more dates on her All I Want For Christmas Is You tour, as she continues to recover from a respiratory infection. 

The tour, which was initially meant to start on November 27th, now wont kick off until December 2nd in New York.

On Instagram the singer explained: ‘I hope everyone had a wonderful Thanksgiving with loved ones; it’s certainly nice to remember what we are grateful for! Like most, I’m thankful for my overall health… for which I need a bit more time to get right.

‘Doctors have ordered a few extra days of rest before I can finally fly to New York and take the stage for my Christmas Tour. While this news disappoints me to share, I am grateful to be on the mend and for the support from all of you - it means the world to me! See you from the stage soon darlings!’

All going to plan the tour will begin on December 2nd with three nights at the Beacon Theatre in New York.

The tour was first scheduled to begin on November 17, but just two days before opening night in Ontario, Canada, Mariah told fans: ‘Lambs! Just in time for the holiday gift-giving season, it seems I’ve received a present of my own; a lovely upper respiratory infection after last week’s flu. Bleak!

‘You know there is nothing I love more than celebrating the holidays with my festive Christmas show, but I have to take my doctor’s orders and rest until he says I can sing on stage,’ she added.

Despite having arguably the most popular festive hit of all time, earlier this month Mariah voiced her objections over being labelled ‘the Queen of Christmas.’

‘It's not that I'm not thrilled. I just don't think I deserve it,’ Mariah told The Hollywood Reporter. ‘I’m just a person who likes Christmas, OK? Who happened to write some songs.’
