Kiefer Sutherland was stunned to discover his friends had hired a male stripper for his birthday.

A nearly naked blonde bombshell slinked in the room, shoved Kiefer down on a chair and began dancing

The '24' actor, whose pals threw him a surprise 42nd birthday party recently, failed to realise the scantily-clad sexy blonde giving him a lap dance wasn't a woman - until the stripper removed his wig.

A source told the National Enquirer magazine: "The lights dimmed and raunchy blues music blared. A nearly naked blonde bombshell slinked in the room, shoved Kiefer down on a chair and began dancing. But at the moment of truth, when Kiefer expected the stripper to remove her leopard print teddy, 'she' ripped off her wig!"

Kiefer was lost for words and hastily pushed the stripper off his lap, much to the amusement of his friends.

The source added: "Kiefer's jaw dropped and he shoved the she-male away as his pals collapsed screaming. He looked angry for a moment, but soon regained his manners and spoke cordially to the stripper."

After the dancer had left the party, Kiefer saw the funny side and unleashed a barrage of good-tempered abuse at his friends.
