Mike Tindall Reveals Prince William's Hilarious Nickname

The royal is known as something other than the Prince of Wales to his pals.

Prince William has a hilarious nickname amongst his friends. During an appearance on the Seven: Rob Burrow podcast, Mike Tindall, who's married to William's cousin, Zara Tindall, revealed what he calls the 41-year-old royal.

"The Prince of Wales is known to me as 'One Pint Willy' because he's 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," Mike, a former pro rugby player, said. "That is one I will definitely give away for the Prince of Wales. One Pint Willy. It's out there now, sorry sir."

Zara laughed at her husband's reveal, jokingly telling him, "You're in so much trouble!"

It's not the first time Mike has let a secret slip about the royals. During a September episode of his The Good, The Bad & The Rugby podcast, Mike revealed that he's seen William's "uber competitive" wife, Kate Middleton, play beer pong.

"I'm not competitive at all," Kate replied in a wry, coy tone, before admitting of herself and her husband, "I don't think we've managed to finish a game of tennis, the two of us. It becomes a mental challenge between the two of us."

In between tennis matches, William and Kate are busy raising their three kids: George, 10, Charlotte, 8, and Louis, 5. The family of five recently released their Christmas card, which features a black-and-white picture of their whole brood.
