Katsuya Sean Penn cargo pants jacket lunch friends car cigarette

Sean Penn took a break from his busy schedule to enjoy dinner with friends at Katsuya in Hollywood, but we couldn't help but notice the 50-year-old actor's multi-colored 'do. Did his bottle of brown hair dye run out early?

Despite the bizarre hair situation, he still looks oh-so-sexy in his cargo pants and black jacket.

Up next, Mr. Penn joins Brad Pitt in the drama Tree of Life. We can't wait to see these two A-listers on the big screen!
