But fear not, Chris Brown isn't getting in trouble for hanging out with a bunch of scantily-clad girls -- it turns out these are girlfriend Karrueche Tran's pals (she's right in the middle in the strappy red shoes).

After dropping $10,000 on Cristal and Ace of Spades champagne to celebrate her birthday at Greystone Manor on Sunday, Chris and Karrueche partied it up at Hyde in West Hollywood last night. Around 5am, Karrueche tweeted, "Best ever," and around the same time Chris posted this shot of his Karrueche rubbing her lady bits on his face and wrote, "Ass ass ass ass ass ass!!! Lol". Such a classy couple...
