George Michael has been forced to cancel the Australian leg of his Symphonica tour following 'major anxiety problems' caused by his battle with pneumonia last year.
Despite a successful run of Europe, George released a statement saying he will be unable to complete his commitments over in Oz.
In the statement he says how it 'breaks his heart' to have to pull out at the last minute but that he underestimated how he would be feeling, despite the doctors warnings.

George wrote: "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."
The singer added that while he has enjoyed his tour so far, however "unfortunately, I seriously underestimated how difficult this year would be".
However, the singer has vowed that he will still tour in the UK in October and until then will undergo treatment to make sure he is well enough to perform.
Our hearts go out to George at this difficult time and we just hope he is feeling better soon.
