Mickey is on some sort of tour, promoting his role in Darren Aronofsky's The Wrestler. Rourke is getting some solid reviews.

And there's absolutely nothing wrong with holding hands with another bloke. Everyone should feel free and comfortable to show friendship, affection and love.

As long as you're not in a public restroom.

Aside from that, are you going to be the jerk to tell Mickey Rourke that he's tarnishing his manly image? 

Mickey brawls! A man with that face feels no pain and cares nothing about what you think. He'll end you!
