Mickey Rourke loves a good pair of shorts shorts!

Wearing a tiny pair of shorts, the headband-wearing actor looked he was feeling the pain as he left a boxing gym in Hollywood on Tuesday. Other than the shorts, we had our eyes on his Pomeranian pal, whom he cradled both to and fro the workout. Too cute!

The Wrestler actor was training with Manny Pacquiao's trainer Freddie Roach -- so it seems as if he's invested in some serious coaching!

Mickey held on to the precious pooch as he left the gym in his blue Bentley. Needless to say, he seems very attached to his four-legged friend!

We are glad to see that the actor has found love yet again after the death of his beloved Chihuahua Loki, who died back in 2009.

At the time, the actor said in a statement to the Daily News, "Loki is deeply missed but with me in spirit. I am very blessed she fell asleep peacefully in my arms."

Glad he's got a new pup!
