Teen popstar Justin Bieber has been accused of getting too big for his rather small boots after he allegedly flew into a swear-word tirade on a TV chat show.

The 16-year-old was appearing on Australian morning chat show Sunrise when he allegedly told a member of the production team "don't ever %$#&*@ touch me again" when he was told where to perform. The heart-throb, who currently has a squeaky clean image, has strenuously denied the allegation, saying he would kill the rumours "with kindness".

But David Koch, co-host of the Australian show, claimed he was less than impressed by the young idol and said he needed "a slap". "Our floor manager was directing him to where he was about to perform and he turned around to [him] and said: 'Don't ever %$#&*@ touch me again'. And then [Bieber's] sound guy... said, 'don't take offence mate he tells us that all the time'."

According to Australian newspaper The Daily Telegraph, seven other employees supported his statement. But the Canadian pop sensation wrote on Twitter that the account was not true, saying: "I was raised to respect others and not gossip...nor answer gossip with anger. I know my friends, family and fans know the person I am. Hearing adults spread lies and rumours is part of the job I guess. But all I have to say is... kill em with kindness."

Bieber was also accused of being 'a diva' at Radio One's Big Weekend in Wales. He reportedly refused to answer any questions about his new tattoo in an interview with Radio One DJ, Fearne Cotton. He is also thought to have driven around in a backstage buggy against event rules.
