According to reports, Karrueche hit up the streets of Paris with a few friends while Chris has been performing a few concerts for his Carpe Diem tour.  Chris Brown and Rihanna have been making their rekindled relationship more and more public in recent weeks, and the fact that Chris was out in Paris with his ex-boo Karrueche while Rihanna was in Germany performing apparently didn't sit too well with Rih. Brown also posted up a picture of Karrueche's clothing line, "The Kill".  

Karrueche posted a series of pictures of her and her friends out and about in the Paris streets, and it was also reported that she was seen partying with Chris Brown.  Rihanna was apparently upset by the news that Chris was spending time with his ex while she was away and tweeted a few angry words, which everyone believes was in response to the situation.  

According to reports coming from The Examiner, a source close to Rihanna spoke up on how stubborn Rihanna is when it comes to Chris Brown, and naive in thinking that he will change.

"She can't get it into her head that Chris will never change.  She's given him so many chances since he beat her up in 2009 and he still keeps hurting her by partying with girls. Letting Karrueche meet him is yet another blow for Rihanna that will further disgust her fans. They are already raging that she is back with him."

After Rihanna posted her series of seemingly angry tweets, she posted up a pic of what appears to be her resting on Chris' arm.
