Mike Tindall's royal relatives including the Prince and Princess of Wales will be "very upset and very sad" by his antics on I'm A Celebrity... Get Me Out Of Here, a royal expert has claimed.
The former rugby player, who is married to Zara Tindall, a niece of King Charles, appears to won over fans since he entered the jungle on Sunday night.
He has already spoken out about how he met his future wife and delighted viewers when he dished on their boozy first date.
And on Monday night's show, he wowed the camp with his rapping skills and knew all of the words to 90s hit Boom! Shake The Room.
But despite it delighting viewers and Mike and Zara known to be close to Prince William and Kate, royal expert and biographer Angela Levin says behind palace walls, they will not be happy.
She told The Sun that William and Kate will be "very upset and very sad" with his stint on the show so far.
And she added: "What's persuaded him? Is it because he's bored and wants to have some fun? Is it because he's desperate to earn more money? I think it brings the royal family into disrepute.
"It was quite embarrassing to do rapping - I don't think that suited him. Why is he there for goodness sake?
"I think that demeans not just his wife, but his mother-in-law Princess Anne - and other members of the royal family. It's not just a joke."
In Monday night's show, Mike revealed how he met his wife - who is the daughter of Princess Anne - in Sydney in 2003.
He told his campmates the pair "went out for lunch locally", which ended up being "quite boozy".
"Then we figure out we both quite like getting smashed," Mike joked.
However, speaking on Good Morning Britain yesterday, culture expert Nick Ede praised Mike's appearance.
He said: "I really think he could be the new King of the jungle because he has got such a great personality.
"You've got to remember he was a celebrity before he was part of the royal family."
Suggesting he was a "rather fantastic man", Nick also said that Mike is a good advert for the royal family particularly as the new series of the controversial Crown gets ready to air.
He concluded: "From a PR point of view this is a great thing for them because all eyes are going to be on The Crown, all eyes are going to be on Harry's book and actually this is a really positive way of showing him as a really fun person who's part of a great family."
