Rihanna and Chris Brown's relationship may be on the rocks again after Chris partied with his ex, Karrueche Tran.
A source told the UK's Sun: "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."
According to reports, Tran plans to follow Chris to the Dubai leg of his "Carpe Diem" tour and Rihanna is fed up.
She sent out a series of angry tweets that said: "Examine what you tolerate," "Goodbye muthaf**ker," and "You give, you get, then you give it the f**k back." The tweets were later deleted.
All may have been forgiven though, because Rihanna later tweeted about missing her man.
No comment from Chris Brown or Rihanna.
