Mike Tindall throws dig at Prince William, reveals saucy nickname: ‘Sorry sir’

It’s wine o’clock somewhere.

Mike Tindall has divulged the nickname he has for Prince William and he believes the Prince of Wales is an epic fail when it comes to throwing back a few beers with the boys.

The former rugby player — who is the husband of Zara Tindall, Princess Anne’s youngest child — revealed the moniker on an episode of fellow sportsman Rob Burrow’s podcast “Seven.”

The 45-year-old joked that he loves to call King Charles’ eldest son, 41, “One Pint Willy.”

Tindall quipped: “He is known to me as ‘One Pint Willy’ because he is not the best of drinkers.

“Coming from a sport where it is built on the social aspect and a couple of beers being sunk quite often. That is one I will give away for the Prince of Wales,” he went on.

“Oh my God. It’s out there now. Sorry sir,” he added.

Zara, 42, also appeared on the radio show and couldn’t help but laugh at the nickname.

“Oh my God. You are in so much trouble,” the equestrian giggled.

Zara, who is William’s cousin and a niece of King Charles, married Tindall in 2011 after dating for eight years.

They have three children: Mia, 9, Lena, 5, and Lucas, 2.

On an episode of the reality show “I’m a Celebrity… Get Me Out Of Here!” Tindall revealed a funny, yet embarrassing, moment he endured when he encountered the princess, 73.

The ex-World Cup winner recalled feeling some shame after “slut dropping” in front of Anne.

The red-faced moment occurred at Zara’s ’70s-themed 30th birthday party.

“I was dancing on the dance floor, I had like flares on, full outfit but it was quite tight, nothing ever fits – rugby player’s bum and legs – so I was dancing with my mother-in-law and I did a slut drop in front of my mother-in-law,” Tindall said on the show.

He continued: “Ripped my trousers, straight in front of her. It happened to be that the boxers that I had on at that time said ‘nibble my nuts.’ ”

“As I’ve turned round, she’s gone, ‘I’d rather not.’ I’ve gone, ‘I’m going,’ and walked off,” Tindall said.

Zara and her man were also present for Charles’ coronation in May.

However, the ex-athlete was annoyed at the time with his seat placement at the illustrious event at Westminster Abbey.

“It was unbelievable to be sat where we were,” he scoffed in an episode of his podcast, “The Good, The Bad & The Rugby.”

“Quite frustrating that you couldn’t see around the corner, but you had the TV there, and obviously everything that went on sort of [in the] back and front.”
