The singer celebrated turning 24 Saturday night with yet another B-day bash at The Mirage's 1OAK nightclub in Las Vegas.
Joined by around 45 friends, Brown hit the club at 1 a.m. and walked the red carpet before heading inside to his private table behind the DJ booth. The Grammy-winner, dressed in all black, partied with a giant birthday cake alongside rapper Fabolous and lots of lady friends until around 3:30 a.m.
While Brown didn't have on-again, off-again girlfriend Karrueche Tran by his side during the party, he did have a Karrueche look-alike gal pal with him during the night. The same blond beauty was also by Brown's side during his Friday night birthday celebration at L.A. Emerson Theater.
During the ZING Vodka and Black Pyramid-sponsored bash, Brown, dressed in a plain white tee, partied with said lady friend and pals.
An eyewitness tells E! News that Tran was indeed part of Brown's entourage when he first arrived at Emerson Theatre on Friday. She was by his side at his table, but she didn't look very happy and later left the party separately from Brown.
Meanwhile, Tran also hit Hennessy V.S.'s "A Night of Music and Art" event with BFF Christina Milian on Friday night at Sonos Studio.
