Rita Ora was accused of having an affair with her boss, Jay-Z, and did not take too kindly to the allegation.

Holly Hagan, who stars on Britain's version of "Jersey Shore", "Geordie Shore," tweeted, “I’ve been told to say that Rita ora has been ALLEGEDLY bukin jay z! I repeat ALLEGEDLY [sic].”

The "R.I.P." singer fired back at Hagan in a number of tweets that were later deleted, but not before British tabloid The Sun captured them.

“You sad Z lister! Stop chatting [expletive] and focus on being a [expletive]!” Ora wrote, before saying, “I stayed silent on one [expletive] rumour but this one I have to speak.”

Ora, 22, probably was referring to her ex-boyfriend, Rob Kardashian, reportedly accusing her of cheating on him with multiple men.

“She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart [sic]? But I mean 20?!!!” Kardashian wrote on his account last month.

He also wrote that he was disgusted that a woman could "give up her body" to 20 men in one year. His sister, Khloe Kardashian, tried to calm Rob down, tweeting, "Rob be nice kiddddd." He since deleted all of the tweets, and later denied he was referring to Ora.

The British pop star was not done responding to Hagan’s allegation, later writing, “Neva eva will any1 including a red head dum z listin attention seekin [] try talk [] about me & my family holly wateva de [expletive] ur name is [sic].

"Anyway I only speak when I have to and that was just [] ridiculous that’s why I spoke…” Ora went on to say.

Ora signed with Jay-Z Roc Nation label when she was just 18 years old.

Hagan then seemed to retract her allegation, tweeting, “Oooopsy getting told off don’t shoot the messenger! Of course I’m only a Z-list why would anyone care what I say ;) night twitter x.”
