Hasselhoff, 53, hit his head on a chandelier in the men's room after using the gym at the Sanderson Hotel in London's West End on Thursday.

His right arm was cut by shards of glass, severing a tendon. A spokeswoman for the former Baywatch and Knight Rider star said he was "out of hospital and ready to continue his work tomorrow".

The actor recently cancelled his debut Christmas pantomime role . . . playing Captain Hook in Peter Pan at the New Wimbledon Theatre, in southwest London.

It clashed with a reality TV series in which he is due to judge aspiring performers alongside former Mirror editor Piers Morgan and singer Brandy.

He is in London filming an advertisement for a British internet company.
