CELEBS BEAT EACH OTHER UP FOR CUBAN’S FUN & PROFIT: Mark Cuban promises his performance on “Dancing With The Stars” won’t be his final foray into reality TV. And them’s fightin’ words:

The NEW YORK POST reports that the Mavericks owner is working to put together a mixed-martial-arts series where “celebs beat the heck out of each other.”Sort of a “Surreal UFC Life.”

Cuban says he’s in development talks with Mario Lopez to help make his dream a reality. And it would be a good way for Mark to vent his frustrations from his ‘Dancing’ drop.

Of course, everyone’s favorite main event would be Cuban facing The Donald in the caged circle. And Mark has already played the first Trump card:

“Donald always picks on people, and a lot of them aren’t in a position to stand up to him….When I stand up to him, I am standing up for all the people who are afraid to. He’s all show and no go.”Trump will fire back, as soon as he’s done dissing the Miami Hurricanes.
