Chris Brown and ex-girlfriend and Karrueche Tran got into a car accident Tuesday.

Then again, maybe she's not his ex-girlfriend anymore.

According to TMZ, Brown hit a Mercedes with his Range Rover while driving in Los Angeles. Tran was a passenger. They stopped and talked to the other driver, who, TMZ said, had "medium" damage to her car.

Brown and Tran reportedly left his Hollywood home and were headed for a recording studio when the accident happened, according to X17 Online. Paparazzi photographed Tran taking pictures of the damage with her phone. The police didn't get involved, but Brown and the unidentified driver exchanged information.

That's great, but the incident prompts a bigger question: How does this guy keep all these ex-girlfriends hanging around?

Brown has a somewhat tainted driving history. In February, the 24-year-old smashed his Porsche into a wall while being pursued by paparazzi. He wasn't injured.

But back to that ex-girlfriend thing.

Brown and Tran are apparently on again after Brown split from Rihanna before his birthday earlier this month.

The New York Post said Brown and Tran were getting cozy at the Billboard Music Awards on Sunday in Las Vegas. Afterward, they were at Bruno Mars' after-party in the Bellagio.

"Brown was standing on the banquette dancing with Tran," a source told the Post. "He bent down a few times to kiss her, and kept running his hand through her hair and singing to her."

Your move, Rihanna.
