Diddy Makes Naomi Catwalk the Plank!

Glamazon Naomi Campbell celebrated her 38th b-day Wednesday by getting into some ridiculous drama!

So when Naomi -- who had been partying on her boat with convicted felon and known con man Christopher Rocancourt (who has admitted to bilking investors out of millions of dollars) -- showed to party on Diddy's yacht in Cannes, the s**t hit the fan!

Sources say the poster child for anger management got into a mayjah confrontation with Diddy -- and he threw a sobbing Naomi off the boat. Happy birthday to you!
