Paramedics were called out to the former Baywatch star’s Californian home by his 17-year-old daughter after he collapsed.
Gossip website TMZ claimed: “Hayley Hasselhoff - who was at home with David - called her mother Pamela, claiming David was extremely drunk. One of Pamela's friends called 911, paramedics arrived at the family's home in Encino and took him to the hospital.”
Emergency services confirmed they had visited the house, but refused to say why.
A spokesperson for the Los Angeles Fire Department said: "We sent an ambulance and a person was transported to a local hospital."
It is believed that David, 57, left hospital last night. He has previously been open about his struggles with alcoholism and was hospitalised for alcohol poisoning in October 2007.
The incident came months after an infamous video – filmed by his family – was leaked, showing him drunkenly writhing around on the floor trying to eat a cheeseburger.
He said afterwards: "Unfortunately, I did have a brief relapse, but part of recovery is relapse. I am a recovering alcoholic."
