"It was love at first sight, such a great experience," Rita Ora dished to The Sun about Bruno Mars. "We met in 2009. I was 18 and starting out at Roc Nation. Bruno was unknown back then too."

Apparently the two stayed together for a while before they got famous and eventually split. "Our time together was wonderful. But once we got famous, work got in the way," the singer explained. "We ended it last year. But we remained close. And when we were together we were so happy."

There you have it. While Rob Kardashian tweets his love for Rita, Bruno Mars can rest easy knowing he had her heart first.
