50 Cent has reignited his old feud with Madonna, this time poking fun at her rear end.

«Who the f*** did this?» the rapper wrote on Instagram, sharing a photo of Madonna next to a cartoon ant. «She’s rich as f***, like, she ain’t fix that? I want the name of the damn doctor right now. I mean, damn, dude! I’m laughing so hard.»

Madonna’s fans rushed to her defense in the comments section, noting that the rapper’s remarks were «completely unfunny.»

«It’s really sad when a man attacks a woman and criticizes her body. Aren’t you ashamed of yourself?» wrote one of them. «Stop making fun of the QUEEN OF POP,» wrote another.
