Chris Brown necklace tattoo singer miami Karrueche Tran chris brown legs bikini miami florida

Despite rumors that he's hooking up with former flame Rihanna (AND that he was at her early birthday party last Monday) Chris Brown and his girlfriend, Karrueche Tran, were spotted in Miami over the weekend. Chris was snapped at his hotel with a rather impressive entourage, and Karrueche and a gal pal hit the beach with a bodyguard, presumably part of Chris' crew.

Wonder why these two aren't stepping out together? And is Karrueche cool with Chris still being so close to Rihanna? Yesterday Chris tweeted, "HAPPY BIRTHDAY ROBYN!", which RiRi retweeted and wrote, "Thanks!"
