‘Model’ Karrueche Tran came home to a surprise from her on-again-off-again boyfriend, Chris Brown, with his signature graffiti plastered all over her Panamera. Usually spray-painting someone’s Porsche would be grounds for dismissal but we’re thinking Chris paid for the Porsche anyway and although Karrueche is pretending to pout in this pic, we think she’ll have a fresh new paint job next week.
