Madonna is under fire from many of her fans who follow her Instagram after using the n-word in a recent caption to a post featuring her son, Rocco.

Proud of her 13-year-old son - whom she had with director Guy Ritchie - the singer shared an image of Rocco boxing, writing, "No one messes with Dirty Soap! Mama said knock you out! #disn**** [sic]." Rapid outrage in her comments over her use of the racial slur prompted her to repost the image with the revised (and unapologetic) caption, "Ok let me start this again. # get off my d*** haters! [sic]."

Although many fans expressed their anger at her actions, some came to her defense, with one fan in particular pointing out that her adoption of her two 8-year-old sons David Banda and Mercy James from Malawi gives her a pass with the word because she "has basically adopted half of Africa."

The controversy comes just a couple weeks after she posted a photo of Rocco brandishing a bottle of gin with the caption, "The party has just begun! Bring it! 2014."

Sounds like some PR people need to keep a better eye on her social networking habits.
