Sir Paul McCartney "can remember being born" but the early memory is "highly dubious".
The Beatles legend made the revelation in a new interview with the Guardian newspaper in which he was asked to recall the earliest sounds he can remember hearing - and McCartney went one step further by revealing he can actually remember sights and sounds from the moment he first arrived in the world in Liverpool, England on 18 June 1942.
He told the publication: "OK, well, now we get into dubious territory, because I have a feeling I can remember being born.
"Highly dubious, highly dubious, but I feel the white tiles and chrome instruments and the sounds … "
McCartney went on to admit it's "almost certainly" an "imagined memory" but it's stayed with him for years.
He said: "It’s probably total bulls***. In fact, it almost certainly is. An imagined memory! And I was a forceps delivery. I don’t quite understand what that is. I think they had to pull me out with some pliers."
It comes after McCartney opened up about the current state of the music industry and compared pop sensation Taylor Swift to the Beatles.
The Yesterday star admitted he can see a "parallel" between Taylor and his band because she has achieved a level of fame comparable to the hysteria which surrounded the Fab Four in the mid-1960s.
During an appearance on BBC show Tracks Of My Years, the musician was asked if he would give any advice to Taylor and he replied: " You do see the parallel, you know the fame and the amount of fame and the worldwide fame that Taylor Swift has and that we had, but I don't think she needs any advice to tell you the truth ... If she asked for it, I definitely would. I'm like the older brother to that generation, or more like the granddad, actually."
McCartney went on to reveal he met Taylor Swift at a party organised by his wife Nancy Shevell and his daughter, fashion designer Stella McCartney which was also attended by a number of other female pop stars including Billie Eilish, Olivia Rodrigo and Sabrina Carpenter - and the Beatles star admitted he was full of admiration for them all.
He said: "I did meet [her] ... We had a party, my wife and my daughter Stella, are very good at getting cool people to a party and I ended up chatting to them all.
"There was Taylor, there was Billie Eilish, there was Olivia Rodrigo, there was Sabrina Carpenter, you know they're really cool people, they're very good. "I like their voices ... If they need any advice, yeah, I would be happy to give it, but I don't think they do."
