George Michael will release new music in 2013.
The 'Careless Whisper' hitmaker - who battled a bout of potentially-fatal pneumonia last year - took to Twitter after fans expressed concern that the normally-prolific user hadn't posted since mid-October and reassured them he was feeling very well and is excited for the coming year.
The 49-year-old star took a break from celebrating with partner Fadi Fawaz to write: "Hey everyone. Belated Happy Xmas. Sorry you haven't heard from your favourite singing greek for so long.
"You needn't worry, I'm doing great. Feeling so much better than I was.
"Must get back to my party, but looking forward to a great 2013, I promise it will be full of great new music, huge Xmas hug to you all. (sic)"
In September, George announced he was axing a string of Australian tour dates scheduled for November in order to receive treatment for "major anxiety" following his traumatic battle with pneumonia late last year.
In a statement, he said: "I have today announced the cancellation of the shows in Australia which breaks my heart.
"By way of explanation all I can say at this time is that since last year's illness I have tried in vain to work my way through the trauma that the doctors who saved my life warned me I would experience.
"They recommended complete rest and the type of post traumatic counselling which is available in cases like mine but I'm afraid I believed (wrongly) that making music and getting out there to perform for the audiences that bring me such joy would be therapy enough in itself.
"Unfortunately I seriously underestimated how difficult this year would be... I was wrong to think I could work my way through the major anxiety that has plagued me since I left Austria last December."
