Prince Charles "took the mick" out of Prince William on his wedding day in a father of the groom speech, it has emerged.
Though details of Prince William and Kate's wedding reception are scant, the duchess's uncle, Gary Goldsmith, has revealed some of what happened when Charles said a few words.
Speaking to ITV on The Day Will and Kate Got Married, he said: "Prince Charles did a great speech, he was taking the mick out of Prince William, talking about him driving a toy car into a tree repeatedly.
"And was very gushing about Catherine."
He added: "I was nervous thinking of Catherine marrying into the Royal Family.
"One doesn't know if she would thrive or survive but it from the moment Charles spoke it was obvious she was being welcomed with open arms and with love so I knew she'd be safe."
The documentary looked back at the royal wedding day of 2011 as the couple, now the Duke and Duchess of Cambridge, mark 10 years of marriage.
They have three children and their lives are markedly different now, even compared to 2011, as they gave up a relatively quiet life in Norfolk to start taking on royal duties full time.
But Kate's uncle was full of praise for how she has handled the lifestyle.
He said: "Kate was born for that role - to humble stock, but totally for that role. She smashes it, they are totally right for the country and I think that's why we love them."
Goldsmith also admitted that his mother, Kate's grandmother, had been a "staunch royalist" and even earned herself the nickname "the duchess".

Reflecting on the wedding day, he said: "It was everything my mum would have dreamt of. I never expected to be at the abbey for a royal wedding and it was one of our family. That was a moment.
"I was beaming with pride, that was our little Kate with Mike, walking up to William."
John Haley, the pub landlord of The Old Boot in Bucklebury, where Kate grew up, also revealed how he was surprised to be invited to the wedding and then managed to get a front row seat, as one chair was left unreserved.
He said: "Carole [Middleton] asked me 'how did you get in the front row?'"
Kate invited many people from her hometown, including the local butchers and the postman.
Haley also recalled a moment as he watched the new couple walk back down the aisle, and became aware of people looking the opposite way to him.
When he turned around, he spotted the Queen looking at him from about five feet away.
