George Michael was rushed to hospital last Thursday following a 999 call made by a close friend, it has been revealed.
Paramedics arrived in two ambulances at his North London home, spending four hours there with the 50-year-old Wham! star.
Four hours later, they sped George away to hospital for further treatment.
Last night his agent refused to say what had caused his mystery collapse, or whether drugs were involved. She also declined to comment on whether the star was still in hospital.
A statement said only: “George Michael was in hospital for routine tests but there is nothing further to say.”
A London 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.”
George, who nearly died of pneumonia in 2011, fell out of a moving car in 2013, and has battled depression and drug addiction, fell ill at home in Highgate, North London, last Thursday.
We wish him a speedy recovery and hope he is well again soon.
