The 22-year-old and reality TV star Kim Kardashian's brother had an ugly break-up as Rob alleged Ora cheated on him through out the relationship, reported Sun Online.
"Honestly I never actually thought it was a relationship. I never mentally defined it as boyfriend or girlfriend. When I split up with him I said 'It's because I'm never there, I don't know how to do it.' That's all I said.
Rob had taken to Twitter post the split to claim that Ora had cheated on him.
