According to the Sunday Mirror, Michael has told prison officers that he does not want to make friends.
A source said: "Everyone calls him The Hermit, because he could mix but has chosen not to. He always watches the Jeremy Kyle Show - he's a big fan."
Michael was transferred to Highpoint Prison, Suffolk to serve the remainder of his eight-week sentence for driving under the influence of drugs.
The insider said that the popstar has refused to use the gym, rarely goes for walks and only enters the communal areas to use the telephone, adding: "I think he just wants to be alone."
