Chris Brown Disses Rihanna AGAIN? Karrueche Tran's Boyfriend Slams RiRi on Twitter for 'Using' His Love after Raunchy 'I'm Still' Diss [LISTEN]

Apparently, Rihanna really hurt Chris Brown (emotionally) while they were dating... bad.

On Sunday (October 20), the "Fine China" crooner tweeted:

@chrisbrown: "Work hard... Spending time has no effect on how much someone loves you. Once they get on... They will find away to get what they want."

Basically, Breezy's saying that he truly loved RiRi, but she just took advantage of his feelings. This Twitter "diss" comes just days after Brown's controversial verse for DJ Khaled's new single "I'm Still" -

Now every n*gga in the industry done f*cked my b*tch, and all my n*ggas said 'I told ya.'

But Breezy's rekindled relationship with aspiring model Karrueche Tran seems to be doing just fine... so he should be happy, right?
