Floyd Mayweather once again proved no one celebrates a birthday better ... the legendary fighter threw a super exclusive party for his 47th trip around the sun, and was gifted an insane $150K watch!
The shindig went down Thursday night at Lush -- David Grutman's spot in Miami -- where Mayweather, who turns 47 on Saturday, hosted 150 of his closest friends, including Nicky Jam ... many of whom TBE flew into town, and put up at a fancy hotel.
