"Hit the Floor" star Stephanie Moseley is dead .... after a murder-suicide involving her rapper boyfriend ... a member of Floyd Mayweather's Money Team ... TMZ has learned.
We're told residents at a swanky L.A. apartment complex near The Grove heard shots ring out early Monday morning. The SWAT team raced to the scene and knocked down the door of an apartment ... and found 2 people shot to death.
The rapper Earl Hayes -- who was once signed to Mayweather's record label -- often partied with Floyd. Moseley has been a backup dancer with numerous singers, including Chris Brown and Britney Spears.
It's unclear who shot who ... but residents heard a woman screaming.
That is heartbreaking, RIP to her I have absolutely no sympathy towards the monster that killed her, mess @ idiots on Twitter saying RIP to him and completely ignoring the innocent girl he murdered!
