Kobe Bryant celebrated an amazing victory Sunday night ... winning an Oscar and, incredibly, the celebrities in the audience had a case of selective amnesia. Kobe took home the Oscar for Best Animated Short Film for "Dear Basketball." The audience cheered Kobe ... some even rose to their feet for a standing O. Interesting ... considering the majority of the audience were wearing Time's Up pins. You may recall -- although a lot of the people who came out after the ceremony didn't -- Kobe was arrested in 2003, charged and tried for rape. The case fell apart when the alleged victim stopped cooperating with prosecutors. Kobe subsequently settled for a reported $5 million, though he denies paying her a cent.
