The former Wham! star, who has served two out of the eight weeks sentence, was found in possession of cannabis and drug- driving following a car crash in north London in July.
"Everyone calls him 'The Hermit' because he could mix but he has chosen not to... I just think he wants to be alone," the Daily Express quoted a source as saying.
But the sources insist that the star isn't interested in making friends during his stint.
Michael was transferred from London's tough Pentonville prison to the Highpoint jail in Suffolk where he will serve out the rest of his sentence.
