FLOYD JR. FLAKES OUT OF OWN FREAKIN’ CHARITY EVENT: RAW VEGAS cooks up news that Floyd Mayweather Jr. didn’t show up to his own charity fundraiser:

The Sin City site had a reporter standing by on the red carpet for the Floyd Mayweather Jr. Foundation event. But he became red with rage himself when Floyd did a no-show.

Among those also not appearing as scheduled were rapper 50 Cent, baller Allen Iverson, actor Jamie Foxx and “singer” Don Johnson.

Now, you *know* the former “Miami Vice” star shouldn’t be busy enough to skip out of this gala celebration.

Well, at least *this* boxer isn’t afraid to make a grand entrance (and exit):

This guy should start a charitable organization of his own, in the hopes of finding a cure for getting in the ring properly.
