[Photo] Chris Brown Rests Face on Karrueche Tran Naked A$$, Wishes Her A Happy Birthday

Looks like Karrueche Tran had a fun birthday. At least that's what we're inferring from this Instagram photo of her naked butt - with Chris Brown's smiling face resting comfortably on that piece. The Pic is from lastyear. Wonder what this year's party would be like... Imagine.
