Chris Brown is on-again with girlfriend Karrueche Tran, but he might have found a novel way to be off-again: Breezy surprised Tran by spray-painting graffiti all over her $90,000 Porsche!

The singer tagged the sports car with graffiti monsters resembling the ones he was recently ordered to remove from the outside of his Hollywood Hills, Calif., home.

On Instagram yesterday, Karrueche posted the above image her sitting sad-faced on top of the colorful car. The accompanying caption was expletive laden: "this is what the f--- I come home to lmao this n---- man."

That "lmao" isn't the only thing making us think that she's not upset with Chris after all: The pair are reportedly currently enjoying a romantic getaway at an as-yet-undisclosed location.
