Ana Matronic thinks Michael Jackson was convinced he would ''live forever''.

The Scissor Sisters singer remembers watching a documentary about the singer - who died of acute Propofol intoxication in June 2009 - where he was asked to contemplate death and seemed baffled by the thought there would come a day when he'd no longer be alive.

She exclusively told BANG Showbiz: ''There is a documentary from years ago and there is one part that I was really shocked by and it wasn't anything that other people were on to.

''There was moment were they asked him, there are looking at a sarcophagus and I think it was in Michael's home; and they are asking do you know where this comes from and he explained it and he said he was interested in Egypt and stuff - and then they asked if that is what he would like to do when he dies. Michael looked at the interviewer like he had two heads; like he had never ever considered dying.

''That for me was sort of the most telling and disconcerting moment of that documentary. It was like he thought he would live forever.''

The 41-year-old star - who has recently released a book, 'Robot Takeover: 100 Iconic Robots of Myth, Popular Culture & Real Life', through publishers Cassell Illustrated - thinks Michael struggled because he was ''robbed'' of his childhood and was unable to ''express himself'' properly.

She added: ''I don't want to say that I feel pity for him or that I feel sorry for him but I do see him as someone who's childhood had been robbed from him.

''He was somebody who had to work from the time he was a baby or you know a very, very young child and his incredibly obvious talent led to his being worked like an adult and I think that he was someone who was not allowed to express himself.''
