The 40-year-old 'Candy' hitmaker shared clips of Field's labour on his official YouTube account, reported Contactmusic.
Williams entertained his fans with amusing videos from the hospital room, including a video which showed him doing a rendition of 'Let It Go' from the hit movie, 'Frozen', whilst his wife appeared to be giving birth.
"I've never been more in love, and I've never been more proud of my wife. She's been absolutely astonishing. The universe has presented itself to us again and it's been a very emotional, amazing few hours and we're really happy and honoured that you experienced the journey with us," he said.
