Music Mogul Birdman spent $14.5 mil in cash money for a Miami mansion the size of a Four Seasons.
The rapper -- who co-founded Cash Money Records -- bought the 19,000-sqaure-foot pad last month -- which sits on the ultra exclusive Palm Island.
The 9-bedroom, 17-bath palace is amazing -- 25-foot-ceilings ... a below ground pool ... an outdoor pool with cabana ... a theater, gym, spa area ... in-house massage room ... 100 feet of waterfront AND a private dock.
Ya know, for your awesome boat.
FUN HOUSE HISTORY: The mansion belonged to music producer Scott Storch until it was taken away from him in foreclosure 2 years ago. It was snatched up by the inventor of Rockstar energy drinks for $6.75 mil ... and then flipped to Birdman for a huge profit.
Oh the rich. We hate them.
