Karl Stefanovic has admitted to having a tattoo that has become associated with Australia's 'bogan' subculture - the Southern Cross.

Tatts amazing: Karl Stefanovic admitted on Nova's Kate Tim and Marty Show to having a a tattoo that has become associated with Australia's 'bogan' subculture - the Southern Cross

The conversation went from speaking about wealth to the types of after school snacks everyone ate - from cheese sticks to Le Snaks.

'We didn’t have those expensive things, we couldn’t afford those expensive things,' Kate said to which Tim said: 'You could all afford Southern Cross tatts.'

With that, Karl made his inked-up admission, saying; 'I’ve got one of those. You should not be laughing at Southern Cross tatts.'

Inked up: 'On my back. On my back shoulder with a dragon and a moat...and a knife,' Karl said, revealing the location of his body art

When the radio trio pressed Karl, he added that the tattoo formed part of a 'confusing' foursome of body art.

'On my back. On my back shoulder with a dragon and a moat...and a knife,' Karl replied.

'That's just confusing - that's the Serbian influence,' Marty said in reference to Karl's heritage.

Odd choice? 'That's just confusing - that's the Serbian influence, ' Marty said in reference to Karl's heritage

Karl also admitted on-air that his father changed the family name to make it sound more Australian.

'Is there a Serbian version of Stefanovic? Have we tidied it up for the Anglo world we live in?' Marty asked.

'Yeah we have,' Karl replied. 'Stefarnonovitch. Sounds more credible doesn't it,' and when Marty asked if the orginal surname caused problems for young Karl at school, the today host added an emphatic yes.

'It did', he said. ' That's why dad changed it to Stefanovic. it sounded more Australian.
