Chris Brown and on-again/off-again lady love Karrueche Tran have moved in together -- but sources say that Chris isn't ready to make the relationship "official," reports HollywoodLife.com.

Aww! I can't wait for a man to love me so much that he will let me move in for free sex but no commitment!

A source told the publication, that Karrueche is living with the felon: “Until he kicks her out. Naw, I’m just playing. But seriously, when she’s not traveling and working overseas, she’s with Chris at his house most of the time. She’s between her apartment in the valley and his house these days and for now, it’s working out for them.”

And while they are shacking up -- the 25-year-old still isn't ready to call the petite lady his "girlfriend," adding, “They’re still chilling and doing what they do but no, it’s still not exactly clear on what the direction the relationship is going in. You know these two, they like it like this.”

While the "Forever" singer may be wavering on the relationship title, he did take to Instagram on Aug. 20, to say that he wants to have a baby with Kae. Along with a pic of his girl, Chris wrote, "@karrueche damn near 5 years and this woman still putting up with my shit. Need to have this baby and stop playing! Lol! My WCW.”

Before you two crazy kids have a baby together -- maybe just have a committed relationship? Just an idea!

The high-profile duo have been dating since 2011 -- and have weathered many storms, sometimes drowning and then miraculously coming back up for air. On Sept. 2, Chris pleaded guilty to assaulting a man in D.C., and of course his lady love was right by his side at court.

Hmm yeah -- we think K has taken the phrase "stand by your man" a little too seriously. Definitely stand by your man in hard times -- as long as those hard times are constantly attacking other humans or refusing to acknowledge your relationship.

Good luck guys, you need it!
