DMX SEEN IN VIDEO RUNNING LAPS IN A DETROIT HOTEL … NAKED

*TMZ got their hands on footage of DMX at a Detroit hotel last weekend. What’s the big deal about that you ask?

Well, he was running laps in the hallway … NAKED. No need to ask why. He says he just felt like doing it. Plain and simple.

The footage begins with DMX walking around a hotel hallway in just his boxer shorts, socks and house arrest ankle bracelet … while a hotel employee removes room service from one of the rooms on the floor.

All of the sudden, X ducks behind a corner with a mischievous grin on his face — drops his shorts — and launches into a full ass naked, dong-out sprint.

Eventually, X returns to the starting line and grabs his drawers … and then casually walks back toward his room as if nothing ever happened. It’s pretty hilarious.
