A former girlfriend of Andy Kaufman has waded into the mystery surrounding the comic's death after his brother allegedly fell victim to a headline-grabbing hoax this week (beg11Nov13).

Michael Kaufman hit the news after giving a speech at the annual Andy Kaufman Awards in New York in which he revealed he had reason to believe his brother could have faked his own death. He then introduced a young woman to the stage claiming she was his brother's daughter.

However, Michael later admitted he fears he has fallen victim to an elaborate hoax and cancelled all media interviews. Subsequent reports have suggested his 'niece' is actually an actress named Alexandra Tatarsky.

The bizarre story has now taken another twist as Kaufman's former lover Lynne Margulies has spoken out to insist she was at the funnyman's bedside when he died from lung cancer aged in 35 back in 1984.

She tells Tmz.com, "I was in the hospital room. I was there. They would have had to switch bodies."

Margulies also insists Kaufman only had one daughter, Maria Bellu-Colonna, who was born in 1969.
