Azalea, whose real name is Amethyst Amelia Kelly, was staying in Las Vegas when she told her more than eight million followers that she paid $54 for the popular American sandwich.
She continued to update fans about the outrageous bill, adding that she was charged an additional $10 for knives and forks.
“I’m not kidding I just got the bill and they charged me and extra 10.08 for knifes and forks which aren’t included free here.... So grilled cheese (that I can eat with my hands) is now 64.08! We love scammers,” her tweet read.
Azalea shared a snap of her eating the expensive everyday meal with the caption “I’m reporting this card stolen.”
She continued to joke, sharing a post of her packing the fork and knife in her suitcase, adding she got a free bucket of ice - with no ice.
“Can’t steal what I have a receipt for!” she said in a separate tweet responding to fans.
