Karrueche Tran vs. Rihanna Beef Ignites Chris Brown Diss [Instagram VIDEO]: Hilarious 'B*tch You Owe Me' Parody Of Sam Smith's' 'Stay With Me' Blasts Ex-Girlfriend?

Rapper Chris Brown has it OUT for ex-girlfriend, Karrueche Tran!

Rihanna's probably rather amused...

Rumors suggest that Breezy recently discovered Tran was completely disloyal during the majority of their relationship, so he dumped her.

An alleged source for the infamous gossip webloid HollywoodLife.com reveals that the "Fine China" crooner never really trusted his model sweetheart, anyway:

"It's sad, but the only one he ever really trusted was Rihanna and that's because she didn't need sh*t from him."

Apparently, Tran was a total Suger Mama. Want proof?

On August 13, Breezy shared this rather amusing video parody of Sam Smith's hit song, "Stay With Me." He totally blasts his former lover (or so it seems):

chrisbrownofficial: "Lol!"

Funny, but pretty evil!

This further proves that Breezy believe Tran was only "using" him for his fortune and fame. During their intense break-up, the hip-hop superstar told her that he was "upset that she didn’t visit him everyday he was in jail and then brought up some bogus stuff about her spending $5,000 of his money on clothes and other stuff while he was in jail."

Eventually Tran calmed him down, but obviously there's still some hostile feelings. 

Will the 26-year-old beauty respond? And what about this rekindled Chrianna buzz?
