The Game Bought Diddy a Ferrari 'Cause He Wasn't a Bitch

The Game is NOT the type who forgets people on his way up the ladder ... just ask Diddy, who's got the keys to a new Ferrari to prove it.

Game was doing some shoe shopping in L.A. this weekend when we asked him about a bigger ticket purchase. Diddy bragged about his red Ferrari from Game on their new track together, "Standing on Ferraris."

Seemed like it could've just been rap bravado for a song, but Game broke it down for us ... explaining why he really did make the $250k purchase!
