Radio host Jackie ‘O’ Henderson branded Katarina ‘the most beautiful girl I’ve ever seen’, prompting Laroi to laugh and say: ‘I agree!’

The Indigenous musician said he’d never expected to fall in love so young, but did so shortly after relocating from Sydney to Los Angeles, where Katarina is based.

‘Around the time that I met her, I just put out the whole F*ck Love project and was not in the vibe of love,’ he said.

‘But I guess… you can’t control some of that type of stuff. It was so ironic.’

Co-host Kyle Sandilands added: ‘Once again it’s proven that when you’re not looking, love comes along at the strangest time.’

‘100 per cent, I agree,’ Laroi replied.
