Mickey Rourke went to Shamrock Social Club in West Hollywood last night to get a new tattoo on his arm, and lucky for the guys inside, the 61-year-old actor was just wearing a vest under his parka, so they had easy access to his shirtless bod.

So what did the Sin City star have to say when asked about Justin Bieber's arrest and tattoos? Mickey mouthed off, "I couldn't give a f*ck!" and then spit on the ground and politely asked photogs not to take his picture while smoking. Despite all that, he was friendly with the guys and he came off as quite charming.

Aside from an argyle sweater vest and a camo jacket, Mickey almost gave us a peek at his junk with his ripped camo pants ... talk about hobo chic!
