Warren Sapp roughs up Derek Hough on ‘Dancing with the Stars’ set?

Did you ‘Dancing with the Stars’ fans catch the finalists group dance that aired last night? Apparently in the finalists group rehearsals a few days prior there was a very tense situation on the DWTS set. TMZ sources say Warren Sapp showed up several hours late for rehearsal. Supposedly when Warren finally arrived mid-rehearsal, he began complaining he was having a hard time following the routine. That didn’t sit well with the rest of the dancers who argued back that it was Warren’s own fault for getting there late. At that point, reportedly ex football star snapped and threw feisty but paper thin Derek Hough against the wall. Derick though wouldn’t back down and there was a stand-off in the dance room until they both cooled off and went back to rehearsing.
