Rita Ora, Rob Kardashian Split: What Was Real Reason For Breakup?

Rita Ora spoke to Glamour Magazine about her split from Rob Kardashian.

According to the Daily Mail, the singer told the magazine that she split with the reality star because her busy schedule prevented them from spending any time together.

'I'm not going out with Rob," Ora said. "We were close for a while, but it didn't work because I was never there. I was like a ghost. I used to get so frustrated with myself and then wonder why I was angry, so I decided it was best to keep it friendly - especially at the moment, when there's so much going on."

Rob Kardashian tweeted about his split with Rita Ora on Monday in a series of nasty messages directed at his ex.

"She cheated on me with nearly 20 dudes while we were together. I wonder how many she'll sleep with now that we apart. But I mean 20?!!! How can a woman who is so busy trying to start her own career have time to be with so many dudes all while in a relationship?!"

The outburst led to the phrase "Rita Whora" trending on Twitter for much of the day on Monday.

Later on Monday, Kardashian continued his vent against Rita Ora by claiming that he got her pregnant, the Daily Mail reported. This tweet came in response to a fake Rita Ora account, who wrote to the E! star, " Rob's d**k was wack, I had to go get it somewhere else.

Rob Kardashian then tweeted back at this fake Rita Ora account, ""So you let me get you pregnant and you let others hit raw."

All of Rob Kardashian's disparaging tweets have since been deleted from his account. Instead, he now has tamer messages like a tweet about the Monday Night Football game between the Giants and Redskins and a photo of a personal manicure at his house.
