I think the issue is that both Ludacris and Ice Cube are actors for various films. When Oprah invited the cast of Crash, it would have been polite to invite Ludacris. Not to perform but as a member of the film cast. Does Oprah have to have them on the show? No... But if she invites the entire cast of the film, except one or even the perception of that action is where the trouble begins. No one wants to be overlooked. Regardless, I'm not an Oprah fan so whether they were on or not, I would have never known
