Lord Alan Sugar has revealed that he’s only ever changed “two or three nappies” despite being a father to two sons and a daughter.

Appearing on an upcoming episode of Piers Morgan’s Life Stories, the business tycoon told the host that he spent most of his children’s early years away working.

He even confessed to missing the moment his wife, Ann Simons, welcomed their eldest, Simon, into the world.

"I was not at the birth. I was playing tennis. And I must admit I was not the modern day father," the 72-year-old told the Good Morning Britain presenter, whom he regularly clashes with on social media.

When Morgan went on to quiz him on how many times he must have changed Simon and his siblings - Daniel and Louise - when they were babies, Sugar replied: “Maybe two or three.

"But by the time we were onto the third, not even Ann changed the nappies. We had help."

Sugar later expressed regret over spending so much time away from his children when they were young, explaining: "I was out working and I wouldn't get home until eight o'clock at night.

"The thing is that we are very normal people. We kept the children grounded and that's why they are normal people.

"That's an achievement. That's bigger than making the hundreds of millions or whatever you want to talk about."

Despite Morgan’s probing, Sugar kept quiet on how much he’s actually worth but joked that he’d be able to write out a £150 million cheque.

While he remain tight-lipped on how much he might have in the bank, Sugar was forthcoming about another thing, responding to the rumours that he’s had cosmetic surgery.

Before the interview begins, The Apprentice star said: “Can I just say something? I’m pulling the rug from under his feet now. Yes! I’ve had my eyes done; I’ve had cosmetic surgery; I did it for vanity – end of.”

Sugar’s Life Stories airs on ITV at 9:35pm on Saturday 22 June.
