Michael had recently completed a two year driving ban
Singer George Michael has said he was "stone cold sober" when he was arrested after a car crash.
The 46-year-old singer was held by police after his silver Land Rover hit an articulated lorry in Berkshire in the early hours of Friday.
He was questioned on suspicion of driving under the influence of drink or drugs, but released without charge a few hours later.
In a statement, Michael said he did not want his family and friends to "worry".
Michael, who was back behind the wheel after completing a two-year driving ban, said: "Neither of us was charged because we were both stone cold sober.
"We both think the other is to blame so this is just an insurance fight.
"I don't want my fans or my family worried by what they are reading all over again."
Police were called to the crash on the A34, two miles north of the M4, at about 0100 BST.
In June 2007 the singer was banned for two years after pleading guilty to driving while unfit through drugs.
He was accused of colliding with three parked cars and driving off without notifying the owners.
He was also twice cautioned for possessing cannabis after being found asleep at the wheel of his car on two separate occasions in 2006.
