Karrueche Moves Back In With Chris!

This girl is just dumb dumb dumb!

TMZ REPORTS 

Call her crazy … but Karrueche Tran and Chris Brown are full-on LIVING TOGETHER … TMZ has learned.

Sources close to the couple tell TMZ … they hooked up days before his 24th birthday earlier this month and she’s been staying at Chris’ Hollywood Hills home ever since.

Though she’s keeping her own apartment — smart — she’s already moved most of her clothes and other personal belongings to his pad.

And it’s not like they’ve been secretive … they’ve been spotted everywhere lately, hitting up the Billboard Awards afterparty and even rear-ending a Mercedes together.

Karrueche’s one persistent scorned lover — when Chris first dumped her back in October for Rihanna  — she vowed to win him back, as TMZ first reported.

So where does this leave Rihanna? RiRi and Breezy officially called it quits a few weeks ago … but they’ve ALWAYS had an on-again, off-again relationship … and Chris has made it no secret — he loves ’em both.  

Hey Karrueche … you ever heard the expression, “Fool me once …”
