The former Coronation Street actress, who is now appearing on Celebrity Big Brother, has revealed she was approached by an actor friend of Prince Philip called James Robertson Justice, who tasked her to find Charles and 'teach him,' The Sun reports.
James Robertson Justice died in 1975 and reportedly told Barrie the invite was the 'ultimate compliment' and to not be 'offended by it,' the Daily Mail reveals.
Barrie explained, 'He was obviously very embarrassed and went round and round in circles before it came out. Finally, he admitted he was one of eight people who had been selected to help ‘launch the royal males into their future life’, as he put it.
'Between them, they had to choose anyone they thought would be suitable to teach Prince Charles about sex, and James had decided that I was suitable.'
Barrie continues, 'He actually said: ‘We don’t really want people who are experienced but on the other hand, well, obviously they have to know the ropes. Frankly, the main thing one needs is a sense of humour and I know you have got that.''
The 82-year-old actress came out as gay when she was 67 and later married crime write Hilary Bonner.
According to reports Barrie met Prince Philip at a club called the Saddle Room in the 50s, and was told that if she accomplished her task with Charles she would become a 'fixture.'
'James indicated that if things went well, I would be a kind of fixture — not a girlfriend, but someone in the background. He said: ‘They [the royals] can’t possibly go off into the world without their own person,’' she claimed.
'Apparently, it was to be a privilege as no payment was offered.'
Barrie ultimately reveals, I had to say '‘no’.'
