The 25-year-old hotel receptionist did not even realise she was in labour and initially just thought she needed the loo.
Nicole, of Wythenshawe, Manchester, said: “I felt the need to push. The next thing I knew he was there on the bathroom floor.”
She and her partner Jack Fallon, also 25, had been watching late-night films.
But at 1.55am Nicole’s waters broke. She puts it down to Jack making her laugh.
Nicole said: “He’d been doing stupid voices and singing Britney Spears, including her first hit Baby One More Time.
“Jack is such a bad singer. He goes completely over the top.
“I was crying with laughter so that must have been what set it off.”
The fastest UK time recorded is said to have been Daisy Stewart, 20, from Dundee, who says she gave birth to 6lb 3oz baby Poppy in fve minutes and just three pushes.
