Rita Ora sparks breakup rumour

Pop star Rita Ora has sparked rumours she has split from her boyfriend Ricky Hilfiger after confessing her heart is "empty".

The R.I.P. hitmaker reportedly set up home with fashion king Tommy Hilfiger's son in London earlier this year (15) to silence reports their romance was on the rocks, but now she has reignited the breakup rumours with her remark at the Billboard Music Awards in Las Vegas on Sunday (17May15).

Speaking on the red carpet at the event, Ora said, "My heart feels a bit empty right now - but let's not go there."

Ora and Hilfiger reportedly began dating last year (14).
