Yesterday at the Australians in Film Breakthrough Awards, actress Abbie Cornish arrived on the red carpet with chestnut brown hair — a far cry from her typical pale blond color. I'm not familiar with Abbie's work, so it's hard for me to judge her based on talent. Unfortunately, I know her best as the woman behind Reese Witherspoon and Ryan Phillippe's breakup — not the sort of unsavory reputation I'm sure she'd hoped for.
