Madonna has been slammed for her use of racist language in a post on Instagram.

She posted a photo of her son Rocco Ritchie boxing on Friday and infuriated her followers by accompanying it with the caption “No one messes with Dirty Soap! Mama said knock you out! #disn***a."

The singer instantly received backlash for using the racially charged term and she swiftly responded by deleting her original post and replacing it with the message: “Ok let me start this again. #get off of my d**k haters!”

Many users expressed their disgust at the fact that she would use such racially charged language having adopted two African-American children.

One such user said: “There are haters. Then there are people offended. Like myself being of the same race as Ur African son. Ur account is public. I know Ur smart enough to know that word originated as offensive. I'm disappointed. I loved u. But I have a line. I'm done."

Madonna herself has yet to comment any further on the controversy she has caused.
