RAPPER’S RUFF ROLE

When “Show Dogs” opens Friday, moviegoers will hear rapper Ludacris lending his voice to a four-legged crime fighter named Max, who works alongside Will Arnett. “I’m voicing a Rottweiler. He’s a police dog,” the “Move B-tch” rapper told the Daily News. “We think of the dog as the sidekick, but the dog thinks the human is the sidekick.” Ludacris (above) also plans to start work on “The Fast and the Furious 9” in March.
