Jack Maynard has been forced to apologise for previously using "inflammatory and insulting language".
The 'I'm A Celebrity... Get Me Out Of Here!' star appeared in the show's latest series launch last night (19.11.17), but away from Australia it was revealed he had posted a number of offensive tweets dating back up to six years ago.
Some of the tweets written on the official account of 22-year-old YouTube sensation - who has 642,000 Twitter followers - featured the N-word, and one also mocked someone's physical appearance.
One tweet, from June 2011, read: "At alices with my n****s! (sic)"
In another message in December 2012, Jack responded to two people, calling them "retarded f****t (sic)".
A few months later, he tweeted someone saying: ""hahaha shutup you f****t... By the way who hit you with a shovel? (sic)"
A spokeswoman for the vlogger - who has more than 1.2 million subscribers on his YouTube page - told The Sun newspaper: "Jack is ashamed of these tweets, many were deleted a long time ago.
"He would never use that language now and realises this kind of retaliatory, inflammatory, insulting language is completely unacceptable."
An ITV spokeswoman said: "Jack has issued a full apology and has deleted the tweets that he sent."
On last night's show, Jack - whose brother is singer Conor Maynard - was paired up with Made in Chelsea's Georgia Toffolo after viewers voted for the stars to buddy up to try to win a meal ticket.
To do so they had to take part in a Walk the Plank challenge 334ft up on the roof of a Gold Coast hotel in Australia.
The pair both completed the challenge, as did Jennie McAlpine, Amir Khan, Vanessa White, and Jamie Lomas.
