“I’d never changed a nappy before I met Bear and all went well brilliantly until five in the morning.
“Bear wakes up and Cheryl changes his nappy – there was poo and spouting wee everywhere!”
While Liam went on to reveal that he only met Cheryl’s dad for the first time when she was pregnant.
The 23-year-old singer admitted that he had to get rid of his “life sized model dinosaurs” that he bought while drunk before the meeting.
“My missus was pregnant and I was meeting her dad for the first time so I thought I had better get rid of the life sized model dinosaurs I had in my garden,” he joked.
“I had bought them drunkenly off the internet!”

While Liam went on to talk about his new music, he said: “A more grown up sound.
