It's no secret that Ja Rule and 50 Cent have this ancient rivalry. Recently, Rule inserted himself in the keyboard brawl happening between Fif and Floyd Mayweather Jr. and definitely has gotten a few laughs in.

Last night, though, the Murder Inc. emcee took his laughter to new levels. Making a joke out of cardboard cutouts of himself and the Power star, Ja Rule sang, "All I need in this life of sin is me and my best friend." He then cackled hysterically, which would be anyone's natural reaction. It was the type of laugh that's contagious. Rule ended the video by panning the camera to a cutout of Diddy and randomly shouting, "Yo Diddy, where you at, n****?"

Let's hope the lighthearted joke settles the score and doesn't ignite another war between the Queens legends.
