DAVID HASSELHOFF was left stunned during a live TV interview on Friday (17Aug12) when his pop pal DONNY OSMOND invaded the set and demanded his autograph.
The Baywatch legend made an appearance on British chat show This Morning and was discussing plans for a movie version of his hit 1990s TV drama when fellow guest Osmond ran into shot.
Osmond leaped onto the sofa where Hasselhoff was sitting, put his head in the actor's lap and said, "Will you sign my hand?".
Hasselhoff was happy to join in the prank, pretending to autograph Osmond's digits before performing a mock heart-resuscitation on him.
The bizarre stunt left Hasselhoff looking bewildered, as Osmond walked off the set, telling him, "I love you, man."
