Ant and Dec shocked I'm A Celeb viewers last night (21 November) after casually revealing that YouTube star Jack Maynard had to "withdraw" from the show, with no explanation.

The 22-year-old social media personality was said to have been extracted from the Australian jungle by his "representatives" due to "circumstances outside camp".

But it is now being reported that Maynard – who is the younger brother of pop singer Conor – will also be quizzed over allegations about sending inappropriate messages to a female fan, The Mirror reports.

The star had already faced controversy this week after The Sun published a series of his past offensive tweets to his young, impressionable following, which insulted gay men and used the N-word. He also branded other users "retarded" and "f***ots".

Some of the tweets dated back to six years ago, and some of them have been deleted.

Maynard's publicist confirmed he was leaving the ITV show so he could be aware of the allegations being made against him and be present to defend himself. He apparently agreed with the decision "made by his representatives and ITV".

J’s face when he got away with the bushtucker trial last night 🦎 Will he be so lucky tonight? 🤷‍♀️😏🐛#JungleJack @itvimacelebrity (📸 @bylukewright)

A spokesperson for the show said: "Due to circumstances outside camp Jack has had to withdraw from the show."

While a statement from Jack's agent said: "In the last few days Jack has been the subject of a succession of media stories which he has been unable to respond to.

"Since it is only fair that everyone should be aware of any allegations made against them and should also have the right to defend themselves, it was agreed it would be better to bring him out.

"Jack agrees with this decision which was made by his representatives and ITV, and thanks everyone who has supported him in the show this far."

Maynard insisted he was not someone who likes arguments before heading into the jungle, telling The Mirror: "I'm not the argumentative type, I try to avoid conflict and turn any negative situation into a funny one or more enjoyable. There's probably a chance I'll be the youngest, so I'll bring a lighter side."

Viewers were also hoping that a romance could brew between him and Made in Chelsea's Georgia Toffolo after the pair were put together for the first task.

Maynard has more than 1.2 million subscribers to his YouTube channel and has a 667K following on Twitter.

The news of Maynard's departure comes as two new celebrities are set to enter camp, radio presenter Iain Lee and Scottish MSP Kezia Dugdale.

I'm A Celeb continues tonight at 9pm on ITV.
