"Guys, I wanna let you know. Nick can't spell and if it wasn't for the love I have for him he would have "BORN REBLE" tatted across his back," she told her six million followers.
"I came in half way thru his tattoo and noticed 'BORN REBEL' looked different to the way I remember it," she continued.
Azalea then said she thought about letting him get the tattoo anyway, before posting photo proof of the spelling mistake.
"He really is lucky I mentioned it to him, I was gonna be petty and not say."
Other celebs with tattoo fails include Hayden Panettiere getting the words, "Live without regrets" permanently inked down her rib cage in Italian, but misspelling the last word, and rapper T-Pain getting a Facebook 'like' button as a tattoo.
