50 Cent doesn't like when he sees Ja Rule still breathing.

So when he saw a video performing at the  Hot in Herre Festival in Toronto, Fif had to clown.

"Lol 😆😆😆WTF 😂I ain’t gotta say sh*t stupid 🥷🏾’s SMH 🤦‍♂," he typed about the set, during which Ja was carried on stage by paramedics and was "revived" to perform his song “Livin’ It Up.”

Ja argues that 50 is too obsessed with him.

"@50 Cent You're like an obsessed side b*tch ... do me a favor and TAKE MY DICK OUT YOUR MOUTH!!! Pause," he typed. "All this back and forth on the internet n*gga we don't tennis that ... YOU GOTTA DO SOMETHING!!"

Is Fif all bark and no bite?
