Ray J’s family and friends gathered in Las Vegas to celebrate his 30th birthday on Saturday night (Jan. 15). The ladies’ man popped bottles at PURE Nightclub at Caesars Palace with his girlfriend Brittany Pena, Snoop Dogg, Floyd Mayweather Jr., and his freshly-inked sister, rocking a music-inspired foot tattoo.

“WARNING: Never get a tattoo on your foot!! This ish HURTS!!!” tweeted Brandy, who serenaded her lil’ bro with “Happy Birthday.”
