Diddy, known for throwing huge parties, was celebrating his new "Last Train to Paris" album in London.  A model who was part of the party, got a little too close to a candle while in the bathtub! Poof! Notice how she dives in to put it out!

Diddy is known for some crazy parties -- but this one went down in flames -- particularly for a model whose hair ignited.
