No 'Hangover' for Mel Gibson, says director Todd Phillips

And his pal Jodie Foster is gonna be so bummed.

Despite the fact that fighter Mike Tyson, a convicted rapist, starred in the first "Hangover," Gibson, who hasn't been convicted of anything  in a court of law, is persona non grata for the sequel.

Reports this week leaked about the actor/director -- now most famous for his foul-mouthed racist, misogynistic phone rants to his ex-girlfriend Oksana Gregorieva -- would play a tattoo artist in the raucous comedy. But now comes news that ... he won't.
