Princess Anne will not only be watching her son-in-law Mike Tindall take part on I’m A Celebrity… Get Me Out of Here! but from the sounds of things, she’ll be loving it.

The rugby player made history being the camp’s first ever royal, as he joins the likes of Lioness Jill Scott, pop icon Boy George and former health secretary Matt Hancock.

While it was previously reported that Prince William and Kate Middleton will be ‘very upset’ about his actions on the reality show, a royal expert has now claimed Princess Anne, who is the younger sister of King Charles III will be enjoying the jungle stint.

Mike married his wife Zara Phillips in July 2011, after he proposed two years before, with the couple now sharing three children: Mia, eight, Lena, four, and Lucas, one.

Expert Jennie Bond said: ‘Princess Anne has more of a sense of humour than we recognise. She can be very stern, but she’s actually one of the most natural people within the family unit.’

She added to OK! Magazine: ‘She will laugh, she will joke and I think she’d probably find his antics in the jungle quite funny. I don’t think she will be offended in the least about the underpants story.

‘She probably won’t watch every night but she’s very close to her children and I imagine she will want to know what’s going on so she can share the experience with Zara.’

This comes after Mike revealed a hilarious moment he almost gave his mother-in-law a cheeky glimpse of his Crown Jewels, after splitting his trousers at a party.

‘I love a suit. My problem with suits is I over exaggerate dancing at weddings… I rip a lot of suits, trousers and stuff,’ he began, before comedian Seann Walsh laughed: ‘Course you do.’

‘The old slut drop gets me every time,’ Mike continued, in a sentence we never thought he would say on national TV.

‘I went to a wedding, ripped a suit, they were like, “Oh my God, what are you going to do?” I was like, “Don’t worry I’ve got a spare.” They were like, “Who brings a spare suit?” Someone who rips a lot of trousers brings a spare suit.

Mike went on to recall the time he was dancing with Princess Anne at wife Zara Phillips’ 30th birthday – and things went from bad to worse.

‘It was a disco 70s themed party, I was dancing on the dancefloor, 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.’

A stunned Seann in the Bush Telegraph said: ‘Mike slut dropped in front of Princess Anne and that is not the end of the story… that’s already, what are you thinking?’

Mike continued: ‘Ripped my trousers, straight in front of her. It happened to be that my 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.’

Who knows what wild royal story Mike will reveal next?

I’m A Celebrity… Get Me Out of Here! continues tonight at 9pm on ITV.
