ARGH! Someone get some vitamin E cream, STAT. It's BRAD PITT'S FACE, IT NEEDS HELP! 

If you reckon it looks like he had a sudden bout of narcolepsy involving an accommodating pavement pillow, that's not far from the facts. 

Speaking at the Autism Speaks benefit, he told People magazine at the event on Saturday night: "This is what happens when you try to run up steps in the dark, with your arms full, wearing flip flops... Turns out if you then try to stop your forward momentum with your face, the result is road rash. Regardless, I wasn't going to miss the Autism Speaks benefit the night after - wonderful people and I was honoured to be a part of this important event."

Other celebs spotted hobnobbing at Light Up the Blues Concert in Hollywood, included Jack Black and Christina Applegate. Neither of them wore their own faces away to bring attention to the event, so they've only been getting a cursory mention.
