Floyd Mayweather -- I Won Big ... So I Party Bigger!!

He already conquered Vegas ... and this weekend Floyd Mayweather has his sights set on the L.A. party scene ... turning up with huge stars in Hollywood for his official victory party ... TMZ Sports has the pics.

Floyd hit club Lure in Tinseltown Friday night and got it crackin' with stars like Bow Wow, Keyshia Cole and Justin Combs with DJ Dirty Draws and Branden King controlling the party.

We're told Floyd wasn't nearly as low key as the last time he was out at Lure ... and turned up the whole night with his gal pal Bad Medina.
