Indeed. One other celeb who's handled it properly is Tiger Woods. Calling him black or african American would insult his mother ... and maybe annoy his blond wife.
Tiger Woods has handled fame and success with more class than anyone in recent memory. I though it was very telling earlier this year when he went through his "slump" while his father was dying, he never once tried to blame anyone for his playing or make any excuses, then he got refocused and came back roaring.
