It may have been a brief romance, but the relationship between Rita Ora and Rob Kardashian certainly had an ugly ending.

On Wednesday (April 23), Ora stopped by Power 105.1's radio show "The Breakfast Club" and was asked head-on what the deal was between her and the "Keeping Up With the Kardashians" star.

"I don't want to talk about this too much because people move onwards and upwards, and it was a phase," Ora said. "And it was a moment in my life and now it's like onwards and upwards."

Back in 2012, the two were seen getting cozy on several occasions, but never publicly admitted to being in a relationship. But in December, the E! star went on a Twitter rant claiming that Ora cheated on him "with nearly 20 dudes."

Ora, who added that Kardashian is "a great dude," had denied ever dating him, but that doesn't mean she wasn't fazed by his Twitter outburst.

"It was a bit where I was like 'Really, dude?' " Ora said when asked about the tweets. "But what I think is that people react to things differently and like to express their feelings in certain ways. I don't tend to use social media, so when that whole situation happened, silence for me is the biggest form of flattery and I love to just keep it moving unless I need to say something."

However, Ora wasn't just put on the spot about Kardashian, she was also pressed about all those pesky rumors that she was once having an affair with Roc Nation boss Jay Z.

"Don't you dare disrespect Beyonce like that ever again in your entire life," Ora said to "The Breakfast Club" hosts. "You should know better than that ... that's just straight up disrespect. You can't even go there."

But Ora had no problem discussing her current boyfriend, Calvin Harris, who produced the British songstress' latest single "I Will Never Let You Down." While the two have no plans to walk down the aisle anytime soon, she is making one very important plan for their future.

"I think [he's] ready for us to go away together, I haven't been away with him in a long time," Ora said. "I want to take my weave out, so it will be nice to spend some quality time."
