Rita Ora, Jonah Hill: Singer Cheated On Rob Kardashian With 'Wall Street' Actor (Report)

The breakup saga between Rita Ora and Rob Kardashian continues, with Jonah Hill now in the mix.

A source revealed to Us Weekly that Kardashian dumped Ora after learning she cheated on him with Hill. "Rita spent the night with Jonah during a trip to New York," the insider said. The two met at a club in the city and allegedly went home together in November.

"I heard she cheated, but I don't know," reality star Nyasha Zimucha, who appeared on "The A-List: New York," told Us Weekly.

Earlier this month, Kardashian took to Twitter to unleash a series of angry tweets about a woman who cheated on him. Ora was never named, but many presumed she was the subject because the two had been romantically linked since the summer.

"She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart? But I mean 20?!!!," Kardashian tweeted, according to "The Insider." "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?!"

In an interview with Glamour U.K., Ora offered a different explanation for the Kardashian breakup.

“I’m not going out with Rob," she 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.”

Ora did admit to having commitment issues. “I think it’s my only weakness. I’m scared of letting my guard down, and if I feel in love with someone now, he’d have to try ten times harder to break it down.”

Hill split from Ali Hoffman, daughter of Dustin Hoffman, in September.
