I'm A Celeb's John Barrowman has broken the rules.

We're just one day into the latest series of I'm A Celebrity...Get Me Out Of Here and it seems that one contestant has broken the rules already. John Barrowman is an actor, singer and presenter who has appeared in a number of high-profile West End shows and he's already proving a big hit with viewers, Since entering the Australian outback where the show is based, he's been putting his vocal cords to good use despite the fact that he was warned not to.

According to OK magazine, he's been having a fabulous time belting out a few hits and forgetting the fact that he was told to avoid doing this. John was interviewed before he travelled to Australia for the reality TV show and revealed that he wasn't supposed to sing or it could prove costly for the I'm A Celeb bosses.

In conversation with The Daily Mail, the 51-year-old said:

"I discussed this with them [the producers], because I like to sing and I may burst out into song – but then they’ll have to get the rights for the song and that’s expensive". "Darling, the songs I sing won’t be cheap ones. I might sing a few of my own to get some residual payments in the bag!"

Rule breaker or no, it looks like John is going to be a popular contestant who can provide some light-hearted entertainment, exactly what you need when the Bushtucker trials become all too much. Roll on tonight's episode...
