George Michael has reportedly been released from a hospital in Vienna.

The 48-year-old singer fell ill with pneumonia in Austria last month. He then reportedly developed a secondary breathing condition and was treated in intensive care.

However, local broadcaster ORF reports that George left the AKH medical facility this morning.

He is believed to have been taken to Vienna Airport in a special ambulance, sparking speculation he will take a flight back to England later today.

The hospital has refused to comment on the reports.

George's doctor Christoph Zielinski recently revealed the star was making a steady recovery from the potentially life-threatening condition.

"We know that he is doing well and we are generally optimistic," he said.

George's boyfriend Fadi Fawaz also raised hopes that the singer would be home in time for Christmas after posting messages on his Twitter account earlier this week.

"Christmas at home. I cannot stop smiling today, the best day ever," he wrote.

"He is getting better and better. Nothing to worry about, happy days."

However, the post was later removed from his Twitter page.

George has been receiving care in Vienna since falling ill and cancelling a scheduled performance in the city in November.

He was forced to postpone the rest of his Symphonica world tour after his hospitalisation.

George has been advised to take a break from his career to ensure he makes a full recovery.
