He's left viewers in hysterics with his hilarious jungle tales.

And John Barrowman had his greatest star tale yet in Tuesday's I'm A Celebrity Get Me Out Of Here, as he told his campmates that he once urinated in Prince Charles' back garden.

The 51-year-old larger-than-life performer admitted that after his unexpected toilet trip, he also stole two champagne glasses from the house, leading his majesty to then jokingly send him four more.

John made the surprise revelations as the campmates were discussing their encounters with royalty, and the former Doctor Who star told of the time he privately performed for the royal couple.

He explained: 'I did a private performance for Charles and Camilla at a party at their house in the country, that's where I peed in Charles' garden because I was having a tour of the garden and couldn't get back to the house.'

John then explained that he cheekily stole two champagne glasses from the house as he was leaving, which resulted in a hilarious gift from His Majesty a few days later.

He said: 'On the way out I took two champagne flutes. I got my friend to put one under the seat and told her no-one would know. 

'Then, two days later, a box arrived at the house in Cardiff from his office of four glasses with a card referencing ''we understand you like them''.

'To this day my dad drinks his whiskey out of those glasses with the fleur de lis on them.' 

Later in the Bush Telegraph John added: 'I mean who wouldn't take a glass if you are doing that, right? Don't tell anybody or they won't have me back!' 

John Barrowman's tale came just a day after he returned to the jungle with a cast on his ankle, following the news that he had sprained it during a fall.

After being taken to the medical centre, doctors reassured John that his ankle was not broken, and thus he was able to return to camp.

John then made a sensational re-arrival to his fellow camp-mates delight, though it remains to be seen whether he will be ruled out of any future Bushtucker Trials.

I'm A Celebrity Get Me Out Of Here continues on Wednesday 5th December at 9pm on ITV.
