David Hasselhoff's publicist has denied reports that the America's Got Talent judge has fallen of the wagon.

US media reports claimed the former Baywatch star had been rushed by ambulance to a hospital in Los Angeles over the weekend.

But a representative for Hasselhoff said the actor "felt his equilibrium was off" and called an ambulance because he could not reach his doctor.

The star was suffering from a bout of dizziness due to the anti-nauseau drugs Antivert and Antabuse, his publicist added.

Hasselfoff has received treatment for alcoholism at various US rebab clinics throughout his career.

In 2007, his daughter Taylor posted a now infamous video of him drunk on a bathroom floor on the internet.

"It's one of those things, it's one day at a time,” the actor said following the incident.
