Armie Hammer has been secretly nursing a broken hand after a drunken night out in Russia.
The Social Network actor and his wife Elizabeth Chambers recently visited Moscow to promote his new movie The Lone Ranger and they were welcomed with a traditional Russian meal.
Hammer's hosts made sure to keep the vodka flowing throughout the special dinner and the star happily indulged - but the 26 year old can't remember what happened afterwards.
He woke up the following morning to find himself covered in blood - and had to grovel to his wife to fill him in on his drunken actions.
Hammer explains, "All I know is I woke up the next morning in our hotel room and the room was covered with blood. And I was just like, 'What did I do?' I couldn't find my wife and I was like, 'Elizabeth, Elizabeth! What's going on?!' I find my wife in the other room, just glaring at me and I go, 'What happened?' and she goes, 'You don't know what happened? You should know what happened'... I look down at my hand and it looked like someone had cut a baseball in half and put it under my hand and it was just dried blood all over.
"Turns out, I was having such a good time that I decided to run down the hallways of our hotel screaming about how much fun Moscow is and then bam! Smacked my hand on a big steel column and broke my hand - ended up in the hospital at Moscow..."
However, the medical emergency hasn't soured Hammer's memories of Moscow: "It is one of the most fun places... it's the best."
