Prince William has revealed the worst gift he's ever given Kate Middleton in a new podcast.

He appeared on BBC Radio Five Live's That Peter Crouch Podcast, and explained just how bad the gift was.

"That was early on in the courtship that was. I wrapped them. They were really nice," William said, according to People. 

"I was trying to convince myself about it. I was like, ‘But these are really amazing, look how far you can see!’ 

"She was looking at me going, ‘They’re binoculars, what’s going on?’ It didn’t go well. Honestly, I have no idea why I bought her a pair of binoculars."

Luckily, the pair seemed to work things out as they got married and have three beautiful children.

Despite being members of the royal family, the Duke and Duchess of Cambridge have had to adjust to the challenges of homeschooling during the coronavirus pandemic.

Prince William admitted that it hasn't been easy.

"My patience is a lot shorter than I thought it was... and my wife has a lot of patience."

He joked about his lack of math knowledge as he tried to help out his children with their homework.

"I was a bit embarrassed about my maths knowledge—I can’t do Year 2 Maths!"
