Peter Andre will challenge contestants to write a 'jungle song' when he heads into camp for a guest appearance on I'm A Celebrity... Get Me Out Of Here!
The singer and TV presenter famously claimed to have written his track Insania during his stint on the show as a contestant in 2004, during which he met his former wife Katie Price.
When he joins the show, he will set the remaining celebrities a task to write a track using bongos, tambourines, and a guitar within an hour. They then have to perform it to receive a treat.
Peter reached number three in the charts with his previous song from the jungle.
He explained the title to fellow contestants at the time: "It's not a word that's actually in the dictionary - it's a new word that is a mixture of insane, and mania."
Andre will surprise the contestants by popping out of a large box wrapped in ribbon following a dance competition which will see them strutting to another of his songs, Mysterious Girl.
After a further challenge, ITV2 star Peter - who had a bitter split from Katie in 2009 - will leave the camp.
