Lightweight Prince William’s cheeky nickname revealed by cousin Mike Tindall: ‘You’re in so much trouble!’

It appears that Prince William can’t hang.

His cousin-in-law Mike Tindall revealed his cheeky nickname for the royal, who is apparently a lightweight when it comes to alcohol.

“The Prince of Wales is known to me as ‘One Pint Willy’ because he’s not the best of drinkers,” the former rugby player, 45, revealed on Wednesday’s episode of the “Seven: Rob Burrow” podcast alongside his wife and William’s first cousin, Zara Tindall.

“Coming from a sport where it is built on the social aspect and a couple of beers being sunk quite often,” he continued. “That is one I will definitely give away for the Prince of Wales. ‘One Pint Willy.’ It’s out there now. Sorry, sir!”

Zara joked that her husband was going to be “in so much trouble” for divulging the sobriquet, adding that “a lot of those nicknames kind of fly around.”

The topic came up after host Rob Burrow asked the couple whether they had any pet names for each other.

“We basically call each other ‘munchkins’ a lot, don’t we? Or ‘my love,’” Mike explained, quipping that he’d leave it to the equestrian, 42, to disclose his contact name in her phone.

Zara — who married the fellow athlete in 2011 — agreed that “munchkin” was one of their most commonly used monikers, but she also refers to him lovingly as “Mikey” or sternly as “Michael Tindall,” specifically when he’s “not listening.”

As for his NSFW contact name, she teased, “He is in my phone as something else, and it ends with ‘kitten.’”

Mike interjected with a laugh, “You can fill the first word in.”

When it comes to boozing, “One Pint Willy,” 41, can’t hold a candle to his younger brother, Prince Harry, who downed six beers while celebrating his 39th birthday at a German brewery in September.

The Duke of Sussex — who was there with his wife, Duchess of Sussex Meghan Markle — made sure to pick up the tab and leave the staff a hefty tip.
