Before Rob Kardashian was detained by police in Miami on Sunday evening, he was seen in an argument with a young woman — and Celebuzz has now positively ID’ed her.

A source tells us that the 25-year-old E! reality star was in a heated discussion with Roc Nation artist Rita Ora when he noticed an on-looking paparazzo.

Rob then tried to chase him down thinking it would be funny, but it ultimately lead to his detainment. Rob has since been released.

Rita, a 21-year-old British singer, is signed with Jay-Z‘s record label Roc Nation and has been making waves with her catchy tunes “Hot Right Now” and “How We Do (Party).”
