Just a few weeks after calling it quits wit Rihanna, Chris Brown is back at it with Karrueche Tran — and they are living together again!

Sources close to the couple say they hooked up a few days before his 24th birthday earlier this month and that she has been chilling at his Hollywood Hills home ever since.

Karrueche is smarly keeping her own apartment — you know, for when Chris' love nest gets to be too much. But she's already moved most of her clothes and other personal belongings to Chris' pad.

The pair has been spotted everywhere recently: a Billboard Awards afterparty and even a little fender-bender.

You may remember that Chris dumped Karrueche back in October to get back with RiRi. She vowed to win him back and it looks like her mission is accomplished.

This could be a bad move for Karrueche because everyone knows that Chris and Rihanna's on-again, off-again relationship is bound to come right back to the forefront.

Let's see what happens next.
