Did Brad Pitt join a real-life fight club?

"This is what happens when you try to run up steps in the dark, with your arms full, wearing flip flops," the father-of-six told ET in a statement. "Turns out if you then try to stop your forward momentum with your face, the result is road rash."

Donning an all-black outfit, Pitt looked to be attempting to cover up his "road rash" with a pair of glasses. "Regardless, I wasn't going to miss the Autism Speaks benefit the night after -- wonderful people and I was honored to be a part of this important event," he added.

Other familiar faces at the event included emcee Jack Black, Christina Applegate, Gary Cole and Amy Brenneman. People also reports that Pitt put in a $23,000 bid for a Fender guitar signed by the performers of the event, all of whom have autism, and won.
