Mickey Rourke's Vladimir Putin Shirts -- This Is Not A Put-On ... I Like Putin

Mickey Rourke has been wandering around Moscow this week sporting not one, but two different Vladimir Putin t-shirts ... and it's no accident ... he's a big fan of the Russian prez.

Rourke put on one of the t-shirts in front of a crowd of people and a few photogs. He said he's met Putin a few times and described him as "a good guy."

The "Sin City" star, who says his current girlfriend is Russian, said the t-shirt is not a political statement and he doesn't "give a f*** about politics."

Clearly.
