Singer George Michael has been injured in a motorway car crash which left another man requiring emergency treatment for trauma.
Michael, 49, is believed to have suffered only minor injuries in last night's collision, which took place during rush-hour at 5.50pm on the northbound carriageway of the M1.
An air ambulance was dispatched to take the trauma victim to a London hospital.
Michael's agent, Connie Filippello, said: "George Michael was a passenger in a vehicle involved in a traffic accident yesterday evening. No third party was involved.
"He is being treated for superficial cuts and bruises but is fine. We have no further comment at this time."
Hertfordshire Air Ambulance was dispatched to the incident, near the junction for the M25, along with East of England Ambulance Service crews from Garston, St Albans and Watford.
Ambulance spokesman Gary Sanderson said: "A man who we believe to be in his 40s sustained a head injury and following treatment, stabilisation and immobilisation by land and air ambulance crews, he was flown to hospital for further care."
Michael - real name Georgios Panayiotou - was handed an eight-week jail sentence in 2010 for crashing his Range Rover while high on cannabis. He was banned from driving for five years and ordered to pay a £1,250 fine.
He had previously crashed his car in 2007, also while under the influence of cannabis .
