Hart vs. Epps Getting Beefy!

First Mike Epps called Kevin Hart overrated ... then Kev threatened to crush Epps' ticket sales by playing the same cities on the same nights as him. 

Yeah, these two are slinging more sirloin than a Texas cattle rancher working the grill at a summer BBQ. In other words ... MAJOR BEEFY!!
