He just can't seem to stay out of trouble!

Following Chris Brown's arrest for assaulting a random fan in Washington D.C. over the weekend, his ex-girlfriend Karrueche Tran took to Twitter and seemingly bashed the R&B star with an ambiguous message.

"What is wrong with some of y'all? Did y'all parents not love y'all enough? Y'all gotta quit with this negative s**t 24 f***ing 7," she wrote after previous tweeting, "I hate waking up to bad news."

The couple broke up last week after the model reportedly pushed the bad boy about moving back in together. "He got really mad and told her, 'Why can't you just be happy with what we got? Why are you always trying to ask for more and more,'" a source told Hollywood Life.

Since he's still on parole from his assault on ex-girlfriend Rihanna, Breezy faces up to four years in prison if convicted of the latest charges against him.

Karrueche didn't let the incident ruin her Halloween, though!

The brunette bombshell dressed up as a "chola" with some gal pals, and while it's not the most politically correct costume, she still looked great!
