DIDDY -- I LOST $1 MILLION To Rapper Rick Ross While Shooting Dice ... And 'It Aint Nothin' He Bragged

Diddy lost a MILLION DOLLARS shooting dice early this morning -- and the best part ... he didn't give two craps about it.

The 43-year-old rapper and entrepreneur - who has a net worth of $580 million – lost the huge sum to Ross shooting dice in a recording studio but bragged ‘it ain’t nothing’. 

The frustrating video from Diddy's dice game was posted on Instagram a few hours ago -- where the rapper bragged about the loss being no sweat and added, "Suck My D**k B*tch."

Rick also uploaded the video to his own Instagram page and captioned it,  ‘I had Puff write me a contract for the 1million $$ I won from him Rollin dice.’

They later took to twitter to share the news with fans, see their tweets after the cut...
