Rita Ora threw a little shade towards her ex-boyfriend Rob Kardashian when she refused to admit that they were ever a couple. 

During a recent phone interview with Kyle and Jackie O on Australia radio station, Kils 1065, the hosts tried to get the Roc Nation singer to talk about Rob, but she remained tight-lipped. 

"I've got no idea what or who you're talking about,'' she said, before laughing on the other end of the phone.

After Kyle tried again to get Ora to say something about Rob, the singer stepped in and said that she didn't want to talk about him.

"Onwards and upwards guys," she said. 

"Honestly, there's a place and time for everything and people change and evolve."

"I think time will tell really and you've just got to keep the train moving forward."

The couple went through a public break-up in December 2012 and months after the split, Ora said she didn't really think they were in a genuine relationship.

"I never thought it was actually a relationship, in all honesty," Rita told Australian newspaper The Sunday Telegraph's Sunday Style magazine in March 2013.

"I never mentally defined it as 'boyfriend, 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, then... the rest happened. He obviously felt that creating myths was the way forward."

Ora has since moved on with Calvin Harris and Rob has struggled with weight gain issues, with many reports indicated it stemmed from his breakup.
