Karrueche Tran denim skirt legs smile greystone manor

Isn't she worried about bumping into ex-boyfriend Chris Brown ... OR his longtime lady love Rihanna?

Last night Karrueche Tran partied it up at Greystone Manor with a mystery dude pal, and the model showed off her tiny frame and her tattoos in a short skirt and cropped top. After getting her fill of dancing and drinks, she tweeted, "McDonalds midnight hour menu is genius." Sounds like someone had the late night munchies! Not sure where it goes though ... she's seriously teeny tiny!

Anyway, it sounds like Ms. Tran has been doing just fine since her split from Brown, as she's set to appear in Cassie's new music video for “Paradise," along with new dad Wiz Khalifa and Diddy. Can't wait to see that!
