After being accused of cheating by her ex, Rob Kardashian, Rita Ora has taken to Twitter to once again defend herself against claims she slept with her mentor Jay-Z. The extramarital accusations were tweeted at the 22-year-old singer by Geordie Shore star Holly Hagan on Wednesday. "I've been told to say that Rita Ora has been ALLEGEDLY bukin jay z! I repeat ALLEDGELY [sic]," the reality star tweeted. "Apparently beyonce is denying claims... But if I gt cheated on I'd also deny it #embarrassing," the flame-haired Hagan wrote before deleting her posts. The How We Do singer, who has been on holiday in Dubai, quickly responded in a series of tweets that were also later removed from her feed. "I stayed silent on one bulls**t rumour but this one I have to speak."

Hagan later hit back, taking pride in her "z-list" status: "You are all thick if u think just because someone's absolutely stunning they won't get cheated on...Cheryl cole? No relationship is perfect." She continued: "Oooopsy getting told off don't shoot the messenger! Of course I'm only a Z-list why would anyone care what I say ;)" "I only tweeted what I'd seen of lots of other people, I didn't call anyone anything, there is no need for death threats though that's sick."

Rita was signed to Jay-Z's label Roc Nation over four years ago, when she was just 18, and frequently hung out with the rapper's wife Beyonce´.
