Floyd Mayweather celebrated his 43rd Birthday in grand fashion Friday night ... with tons of celebs to help him out.
Floyd and co. shut down the Sunset Eden nightclub in Hollywood where hundreds of folks lit up the room, including Snoop Dogg, French Montana, Lil' Kim, Reggie Bush, Tiffany Haddish and Quavo.
A little surprising ... no grub and a cash bar. They did spring for a DJ, who played music all night.
There were strippers riding "Air Mayweather" planes flying up and down with smoke and fire.
