Audience members at the Andy Kaufman Awards were apparently uncertain how to take Michael's revelation.

"The entire room was freaked out," wrote comedian Killy Dwyer on her Facebook page.

"I get that it is - could - might all be a hoax.... [but] it was as real as anything I've ever seen. There is video. It was chilling, upsetting and absolutely intriguing."

Award show producer Al Parinello told the Hollywood Reporter: "I witnessed the entire thing and I can tell you without a doubt this was not a prank."

"You could see by the look on [Michael's] face that it had an emotional impact on him," said Ed Cavanagh, manager at the Gotham Comedy Club, where the award show took place.

But, he added: "I don't know whether somebody is perpetrating something on [Michael] or not. I'm truly 50-50 on this one."

In a video posted on gossip site TMZ, Michael is seen asking whether his brother Andy is "getting close to revealing himself" before the woman covers her face and says "I don't know what to say."

"I mean, he was really thinking about coming," she adds.

Michael then asks the audience not to follow the woman after she left the building.

"I won't give you her name. I don't even know [her] name," he says. "Let her have her privacy."

"Send him my love."

The whole video is pretty awkward and the 'daughter' certainly has something of the actress about her. However, TMZ.com has done a little digging and there's shreds of information that appear to corroborate what she has to say. Notably, that two addresses - one in Cook County, Illinois and another in Westchester County, New York - were listed as the home of a one Mr Andy Kaufman in 2001.

So what do you guys think? Is Andy Kaufman alive?
