I feel let down and betrayed after hearing claims that I’m A Celebrity contestant Timmy Mallett did not actually sing his hit single, ‘Itsy Bisty Teeny Weeny Yellow Polka Dot Bikini’.

Teacher Everton Barnes, 45, told The Sun that he sang all the vocals on the track, because Timmy could not sing.

He said: “The producers decided Timmy was the perfect bloke to do the vocals as he was all the rage.

“But when they got him into the studio they realised his voice was as flat as a punctured pancake.

“There was no way that the record company could release it as it was.”

“I sang the whole vocal track and Timmy’s was shunted into the background.

“I didn’t want anybody knowing as it was a bit embarrassing and I still had ambitions in the music business.”

Everton made less than £5,000 in royalties despite the song making it as number one in the charts for three weeks.

He said: “I’ve decided to speak out as I feel it’s a great shame Timmy is going around singing the song when he knows it’s not his voice on it.

“It was even my idea to insert the ‘Oh yeahs’ and now Timmy is going around shouting ‘Oh yeah’ in the jungle as if it was all down to him.”
