Singer George Michael is back home in London after being released from a Vienna hospital on Thursday.

Speaking outside his home in north London, Michael thanked his doctors and fans for helping him through a “touch and go” bout with pneumonia.

Looking weak, the Faith singer said that “it was by far the worst month of my life, but I'm incredibly, incredibly fortunate to be here.”

“I had streptococcal-something pneumonia,” he said with a laugh. “I spent ten days since I woke up thanking people for keeping me alive in the ICU.”

Michael was rushed to hospital on November 20, forcing the singer to postpone the remainder of his Symphonica European tour.

Early reports suggested Michael's condition was very severe and would require months' worth of hospitalization.

“I'm very weak but I feel amazing,” the AP reported Michael as saying.

Michael announced his new symphony orchestra-backed tour in May during a press conference at London's Royal Opera House. He also said he would be recording a new album during breaks on the tour.
