During a previous interview with The Kyle and Jackie O Show, Laroi revealed how he first met his girlfriend.

The native Australian hip-hop star said he never expected to fall in love so young, but he did shortly after moving from Sydney to LA, where Katarina lives.

“We met through a mutual friend I had when I got here,” he said.

“Around the time I met her, I just released the whole F*ck Love project and wasn’t in the mood for love. But things like that are out of your control. It was so ironic.’
