Former Baywatch star David Hasselhoff has played down reports he was hospitalized over the weekend suffering from alcohol poisoning.

The America's Got Talent judge was admitted to the Cedars-Sinai Medical Center in Los Angeles on Saturday night - with reports claiming he was in a serious condition.

Radar Online reported that Hasselhoff collapsed at his Encino, California home and was found by his 16-year-old daughter Hayley, who alerted his ex-wife Pamela Bach and took him to hospital.

But Hasselhoff's representatives insist the incident was not serious, revealing the star was quickly discharged and spent Sunday night celebrating his father's birthday.

His rep Judy Katz tells TMZ.com, "(Hasselhoff) is fine and well and happy and is celebrating his father, Joe Hasselhoff's 80th birthday tonight at dinner... along with his girlfriend, Kimberly."

The star's lawyer, Mel Goldsman, has also hit out at the reports - accusing Bach of leaking the story to the press and vowing to pursue the matter in court.

He adds, "(Bach) in violation of the court's order precluding contacting the media regarding her ex husband."

Hasselhoff's alcohol problems were exposed in 2007 when home video footage of the star in a drunken state leaked onto the internet.

The 56-year-old later checked into a rehabilitation facility in a bid to kick his drink demons.
