Practice makes perfect, that's what Chris Brown always says.  OK, we don't know if he really says that or not, but he does seem to be pushing his artistic boundaries. 

Just over a month after upset neighbors successfully forced the singer to remove graffiti monsters from the side of his Hollywood Hills home, he created a few more — this time, on his $90,000 Porsche. 

While it seems Chris was fairly pleased with his artwork, his currently on-again girlfriend, Karrueche Tran, looked more shocked than impressed when she first discovered Brown's latest canvas.

She posted a photo on Instagram of herself perched on the hood of the luxury, cartoon-covered sports car with the caption, "this is what the f*** I come home to lmao this n**** man."  In the snapshot, though, she's pouting more than laughing. 

Still, a few monster cartoons on the side of a car — which was also photographed by X17online — that costs more than most people make in a year wasn't enough to deter the model from joining her beau on a romantic getaway, which it seems the singer sorely needed. 

Just a few weeks ago, Brown suffered a seizure at the Record Plant recording studio in Hollywood, which his team blamed on severe stress and fatigue caused by the "constant onslaught of legal matters."  No word as to whether those legal matters included The Los Angeles Department of Building and Safety forcing him to paint over the "artwork" he had added to the side of his house, however.

At least Tran took the Porsche's new paint job (mostly) in stride.  Both she and Chris were dressed in casual, sporty styles as they grabbed their luggage and prepared to head out of the city. 

It is worth noting, however, that they left the monstermobile at home and instead departed in a more subdued black SUV.  Something tells us Karrueche was pretty happy about that.
