Back in April, Ora apparently said that the track - which was written and produced by Harris - was offered to her before Chezza, but she didn't want to record a dance song.
The R.I.P. singer was quoted by The Sun as saying: "I heard Call My Name quite a while ago because I was offered it. I turned it down. I do like the song but I didn’t want to sing it ’cos it’s not really me.
"I don’t want to go down the dance route that a lot of other pop stars are doing. I prefer to have my own sound and do my own thing.”
After hearing about Rita's comments, Calvin took to Twitter to dismiss her claims, tweeting: "For the record, Call My Name was never given to Rita Ora to sing...she made that up, don’t know why. Read it on Wikipedia just then, its crazy how news stories become facts like that!"
Seeing Calvin's tweet, Rita hit back on the social-networking site, stating: "See what I dn’t understand is y dn’t people @ your name when they talk about u? So for the record’ don’t believe media when they twist s***."
Harris then challenged the Hot Right Now star directly, posting: "@RitaOra here calm down! I was setting the record straight as you didn’t at the time. It was a disrespectful comment to make, that’s all."
The Let's Go hitmaker was then asked by a follower whether he had any proof that Call My Name was not offered to Rita, to which he replied: "Cos i did that song."
Ora soon backed down, with the 21-year old tweeting: "I hate beef and fighting.. So I love u all @calvinharris call me ill explain wat actually happened they twisted it and congratulations. X"
Harris added: "@RitaOra me too, thank you luv + good luck with everything!"
