Princess Anne's Reaction To Seeing Her Son-In-Law's NSFW Boxers Is Simply Legendary

Mike Tindall, a former England Rugby Union star and member of the British Royals who is currently a contestant on the British reality show, I’m a Celebrity ... Get Me Out of Here!, shared a hilarious anecdote from his past that involved his mother-in-law, Princess Anne.

Tindall is married to Princess Anne's daughter, Zara Phillips, the daughter of Anne, Princess Royal, and the eldest niece of King Charles III.

Philiips also happens to be the eldest granddaughter of Queen Elizabeth II and Prince Philip, Duke of Edinburgh.

On an episode of the show in which a number of celebs live in a jungle setting and compete to be crowned "King" or "Queen of the Jungle," Tindall regaled his fellow contestants with an embarrassing situation that happened a few years ago at his wife's 30th birthday party.

The theme of the festivities was 70s disco, and his manner of dress wound up not being one for much success.

Tindall recalled:

"I was dancing on the dance floor. I had flares on―full outfit―but it was quite tight.”

"Nothing ever fits a rugby player’s bum and legs.”

The unthinkable happened while he was dancing provocatively with his mother-in-law and attempted a sl*tdrop–a maneuver that involves squatting as quickly as possible and then popping back up.

While he may have physically succeeded with the move, given his athletic agility, his trousers didn't fare so well.

They split apart in front of the Princess Royal and revealed a NSFW message on his boxers.

Awkward.

"It happened to be that my boxers I had on at that time said, "Nibble my nuts," said Tindall.

His fellow contestants were left in stitches.

When he turned around, he said the Princess Royal responded to him with:

"I'd rather not."

Being mortified after the surprise reveal, Tindall agreed and said, "Yeah, I'm going," and the two parted ways.

This season in addition to Tindall, the contestant lineup for the show included high-profile personalities, Boy George, Sue Cleaver, Owen Warner, Jill Scott MBE, Chris Moyles, Charlene White, Babatúndé Aléshé, Scarlette Douglas and Olivia Attwood.

When Tindall's participation in the reality competition was announced, he said:

"I am fully aware that anyone who has ever played rugby will go, 'Yeah let's stitch him up.'"

"All my friendship group has that sort of humour and I know they will definitely want to vote for me! I am prepared to do quite a lot of challenges."

The popular program–which returned to its location in Australia after pandemic restrictions limited production to being filmed at Gwrych Castle in Wales for two seasons–just aired its second episode on ITV after its premier on November 6.

Viewers will have to keep watching to find out if Tindall will spill more tea about life with the Royals.
