Awkward! Kim Kardashian Hits Same Party As Brother Rob’s Ex Rita Ora At Paris Fashion Week

Kim Kardashian must have had an awkward run-in with brother Rob Kardashian’s ex girlfriend Rita Ora as they both partied at the Mademoiselle C Party in Paris last night, following the premiere of the fashion movie.

Rita and Rob dated on off for nearly a year, before splitting in December 2012 where the Keeping Up With Kardashians star took to Twitter to accuse the Hot Right Now of cheating on him with “20 dudes”.

So we can’t imagine Kim, who is known to be protective of her little brother, would be too happy to see the singer, now dating DJ producer Calvin Harris at the exclusive fashion event.

Both of the stars were spotted leaving the party, thrown by former French Vogue editor Carine Roitfeld’s after party at ‘Le Doyen’ restaurant. Rita and Kim have been in the French capital for fashion week, but as yet have managed to avoid each other.

The stars went for very different looks for the evening out. The Hot Right Now singer not only donned a white buttoned up shirt and black trousers for the party, but also a tartan cap and black lace veil – we wonder if she was trying to hide? New mum Kim on the other hand let it all hang out, in a daring cutaway black Givenchy gown which showcased her showstopping cleavage, just three months after giving birth to baby daughter North.

Kim is known to have tried to help Rob after he broke up with Rita last year and in scenes from Kourtney and Kim Take Miami aired in March, show a distraught Rob explaining why he’d publicly blasted the British singer following their split.

In the episode Kim tells her brother: “Don’t post anything else, everyone has problems.”

She also confesses to the cameras: “Ever since Rob has broken up with his girlfriend he has been dating all these girls that I don’t think are his type.”

Rob later explained why he decided to launch such a public attack, stating on the E! series: “I posted what I posted to keep myself from taking her back. Every time she messed up, I took her back for over a year now. I just had to do that to make her hate me.”

Despite Rob’s claims, Rita insisted in an interview they were never officially together.

“I never thought it was actually a relationship, in all honesty,” she told the Australian Sunday Telegraph’s Sunday Style magazine in March.

“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.”

Referring to airing feelings on Twitter, making a thinly veiled stab at Rob, she said: “When you are involved with someone for a while and they decide to express their feelings to the public, well, that’s not my personal way of therapy but I guess everyone takes split-ups differently.

“You should have to sit an exam before you go on Twitter. To see if you’re mentally stable.”
