Amidst heartfelt emotions while discussing their family plans, he expressed his gratitude for parenthood: "It's beautiful because you've experienced it, how lucky. When I think of people who can't have children, and I'm thinking I've got to experience it that many times."

However, the 52-year-old revealed they had made the decision not to expand their brood further due to "complications" during the birth of their daughter Arabella last year.

He said: "Emily had a real complication with Belle which I'm sure she'll tell you about, which people didn't know about, and I don't know if she's ever talked about it, but the complications that happened after, that were very serious."
