Blade Runner and Ace Ventura: Pet Detective actress Sean Young was reportedly taken into custody at last night's post-Oscar Governors Ball "for investigation of misdemeanor battery" (translation: a fight). Young posted $20,000 bail and was released, according to Los Angeles police, who did not release further details. This is not Young's first awards party incident. She was kicked out of the Directors Guild of America awards in 2008 and subsequently entered rehab for alcohol abuse. (She also once tried to crash the Vanity Fair party, but who hasn't.) Anyway, citizen's arrests — they actually work. Now you know.
