Liam Payne talked about changing his son’s nappy on The Graham Norton Show tonight.
In this evening's show, Graham was joined by actress Salma Hayek, who stars in new comedy drama Beatriz at Dinner, comedian and writer David Walliams, who talks about his book The World's Worst Children 2, the stars of new BBC comedy White Gold Ed Westwick and James Buckley, and Liam Payne, who performed new single Strip That Down.
While on the show, Liam also spoke about life at home with his new son Bear.
Speaking about the birth with girlfriend Cheryl, Liam recalled: "It was the most amazing thing."
As for how he'd been coping since, Liam spoke about changing his son's nappy: "I had never changed a nappy before I met Bear.
"I spent the whole day doing the nappy changing business, I hadn't been wee'd on, we struck a deal," he joked.
However Cheryl wasn't so lucky.
"At 5AM, Bear woke up and my missus was like 'I'll do this one', her first nappy change and he'd pooed, the first time it's happened. Then he starts sprouting off weeing. In my head there was music and slow-mo going on. I think it was very ironic after she did all the hard work."
The Graham Norton Show 2017 airs on BBC One.
