George Michael's friends has revealed that the singer has shut himself off from the world and has become a loner after he was taken to hospital after a mystery collapse few months back.
A friend of the 51-year-old singer said that people were worried sick about him and the singer had just cut himself off from everyone, the Mirror reported.
Another friend of the Brit musician said that Michael came close to death in 2011 when he collapsed with severe pneumonia before a Vienna concert on his Symphonica tour.
A friend also spilled the beans that Michael had gone off the radar after splitting with his boyfriend Kenny Goss in 2009.
A friend said that Michael watched tons of DVDs, had staff to book his favorite meals, such as pasta, and spent a lot of his time in his recording space writing but he turned down offers to collaborate with others.
