*50 Cent is using social media to rub in the fact that his former BFF Floyd Mayweather’s ex-girlfriend is currently dating Nelly, saying that the rapper, “really took your lady.”

The whole thing started when 50 posted a pic of Floyd’s ex-GF Shantel Jackson — writing, “CHAMP I ain’t gonna lie this motherf**ker bad. You need to start operation GET THE B*TCH BACK. Right now!!!”

Then he fired another shot, posting a pic of “Miss Jackson” with her boyfriend Nelly with the caption, “Nelly put this up @floydmayweather DAMN da n**ga really took your lady Champ.”
