Chris Brown Graffitis Karrueche Tran's Car, Act of Love?

Karrueche Tran, the off-and-on again girlfriend of Chris Brown, recently revealed that the singer spray painted her Porsche with graffiti which may have been a symbol of the singer's feelings about the model.

Tran, 25, posted an image of her white car painted with 24-year-old Brown's signature graffiti characters, one blue monster with razor sharp teeth on the hood with the smaller pink version on the side of the car.

"..this what the (expletive) I come home to," Brown tweeted while expressing her laughter. "..this (expletive) man."

However, there may be more to Brown's graffiti than what meets the eye. Brown may have painted Tran's car to express his gratitude for her sticking by him during tough times.

"This was his way of thanking her for always being by his side, having his back and helping him through his pain," a source close to the pair told recently. "He already pretty much gave Karrueche everything she ever asked for, and he thought a custom paint job would be different and one of a kind."

After the singer suffered a recent non-epileptic seizure, Tran publicly expressed that she was praying for him.

"Prayers all day," Tran tweeted when Brown's seizure made headlines. " A lot on my mind today .. I need a hug."

After Brown let the world know that he previously planned to break things off to pursue his ex-girlfriend and Rihanna, Tran let it be known that she would always be his friend.

"At the end of the day, he will always be a friend," Tran previously told Vibe magazine. "We'll always care about each other."

Although it is unclear whether Brown and Tran are romantically involved, the singer declared that he would focus on his music as a single man last month.

"[Fans have] seen me on and off again with different girls, you know who they are, but right now, as a 24-year-old man, I just choose to be single," Brown told previously.
