Two ambulances with paramedics were called to George Michael’s mansion last Thursday morning at 8 a.m. A friend had called 999.
The paramedics were at his home for four hours before leaving with George Michael at about noon.
His agent refused to say what caused the collapse or whether George Michael was still in the hospital, according to the Mirror.
A statement said only: “George Michael was in hospital for routine tests.”
An Ambulance Service spokesman said: “We were called just before 8am. We sent two ambulance crews and staff treated a man, who was taken to hospital.”
