The former 'Baywatch' actor is starring as cross-dressing director Roger DeBris in the Las Vegas production of hit Broadway musical 'The Producers' and is struggling with the costume.
Hasselhoff said: 'Now I know why women can't wait to get out of heels.
'I'll only wear the two inch pumps, if I wore the three inch I'd fall over like a giraffe.' The actor also has to wear a 35lb beaded-gown for the part, along with a red wig.
He added: 'I look like Dennis Rodman on acid.' Hasselhoff, 54, admits he was initially unsure about accepting the cross-dressing role.
After deciding to play a transvestite, the actor realised most of his roles have been strange.
He said: 'I never thought I'd be talking to a car in 'Knight Rider', or achieve syndication history with a crazy show like 'Baywatch'.' Hasselhoff has decorated his dressing room backstage with life-size cut-outs and posters of himself in 'Baywatch' and 'Knight Rider'.
He said: 'I must be the most self-indulgent person to have this stuff. But I've got to market 'The Hoff'.'
