Robert Downey Jr. is best known for his acting roles in Hollywood blockbusters from Iron Man to Chaplin to Natural Born Killers — and for his stints in prison on drug charges — but few know the actor can seriously sing.

But Downey Jr. proved he has some serious musical chops when he took to the stage with Sting at the Police front man's 60th birthday concert in New York and sang the classic "Driven To Tears."

In it, he belts out the melodies, harmonizes with Sting and even throws in a few variations of his own.

The concert happened a couple years back, but now the amazing video is (deservedly) making the rounds on the internet.
