Kate Middleton and Prince William's son had recently celebrated his birthday. Prince George turned three on 22 July.
The Duke of Cambridge was asked what gifts the royal child received while attending the America's Cup World Series in Portsmouth. Prince William said: "What did he get for his birthday? I'm not telling. He got too many things. He's far too spoilt. He's not into boats yet."
Meanwhile, the 34-year-old royal had previously talked about fatherhood in a documentary with TV personalities Anthony McPartlin and Declan Donnelly. He said: "I'm a lot more emotional than I used to be, weirdly. I never used to get too wound up or worried about things. But now the smallest little things, you well up a little more, you get affected by the sort of things that happen around the world whatever a lot more, I think, as a father."
"Just because you realise how precious life is and it puts it all in perspective," he explained. "The idea of not being around to see your children grow up and stuff like that. I remember my mother and father taking us to charities and organisations and showing us what goes on. And I think seeing such a broad spectrum of life is really important from a young age to give you a bit of perspective.
"You don't just live in a palace, it's very important you get out and you see what goes on in the real world," he added.
