Hugh Hanley "accidentally" filmed Michelle Heaton giving birth to their baby boy last month.
The Liberty X singer welcomed her son Aaron Jay, known as AJ, into the world on February 28 and proud father Hugh began recording the special moment when the doctor called him over to where he had been carrying out a caesarian section, thinking he was about to capture their little boy's first minutes on film.
To his surprise, Hugh, who presumed they had the baby "out" found medical staff were still assisting in "plucking him out".
Michelle explained to Britain's OK! magazine: "Within two minutes [of the epidural] AJ was born at 8.49am. Hugh's got the video to prove it..."
He added: "By mistake. Michelle was stuck lying there and she couldn't see, so I had the camera ready. The doctor said, 'Hugh, are you ready?' and I presumed they had him out, but when I went over they were just plucking him out so I've got that moment on video."
Hugh then sent the video to his mother via mobile messaging service What'sApp, much to Michelle's horror.
She added: "Have you ever seen a whale being cut open? ... We didn't realise how graphic it was. I'm OK with blood and guts but Hugh What'sApp'd it to his mum by mistake. I was like 'Delete it now, before she sees it, it's too much'."
Michelle was overcome with happiness and emotion when she first held AJ and the pair - who already have two-year-old daughter Faith - admitted there were tears on "both sides".
She added: "It was hard - I couldn't hold him because they were still operating on me and stapling me up, so I stroked his face and burst into tears."
Asked who cried more, Hugh explained: "Michelle, as always, but there were tears on both sides."
