Yesterday, we heard that KARRUECHE TRAN had broken up with CHRIS BROWN.  Well, Chris Brown is now confirming that it's over . . . but he says HE did the dumping.

 

 

--He says, quote, "I have decided to be single to focus on my career.  I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna.

 

 

--"I'd rather be single allowing us to both be happy in our lives."
