If there's one source we trust to know who's been good and who's been bad (aside from our own Naughty But Nice columnist Rob Shuter), it's RadarOnline.com. Breaking Mel Gibson's racist rants and sharing inspiring photos of stars volunteering in places like Ethiopia, Haiti and New Orleans, Radar is a bona fide authority on which celebrities can expect gifts and who can expect coal in their stockings this year.

Who's Been Bad?

Mel Gibson
Mel Gibson's caught-on-tape meltdown catapults him to the top of this year's naughty list, as the Oscar winner inadvertently starred in an instant horror classic. The Mel tapes, published exclusively by RadarOnline, featured the actor coming unhinged for nearly 30 minutes of ranting, raving, screaming and bizarre heavy breathing, plus racist and misogynist comments. It all happened during his breakup from Oksana Grigorieva, and while romances come and go, some things, like audio, last forever.
