Rihanna and Chris Brown had a spat over the weekend.

Rihanna is angry that Brown partied with his ex-girlfriend, model Karrueche Tran, on Friday night after his show in Paris, according to The Sun.

"She can't get it into her head that Chris will never change," a source told the British tabloid. "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."

Rihanna supposedly sent out a series of angry tweets, according to Hollywood Life, saying "Examine what you tolerate," "Goodbye mutha (expletive)," and "You give, you get, then you give it the (expletive) back." These tweets appear to have been deleted.

Can you imagine what life was like before Twitter, when people didn't communicate?

Hollywood Life reported Tran plans to follow Brown to the Dubai leg of his "Carpe Diem" tour. Rihanna is supposedly fed up.

Of course she is.

"She was meant to stay with Chris in Paris -- but it looks like she gave it a miss and will head straight to Manchester tonight to perform on the 'X Factor' final's results show," the source told The Sun

Of course, not long after Rihanna sent out the angry tweets, she later tweeted about missing her man.

Call me crazy, but does anyone else see a pattern here?

The Sun also reported that the level-headed Rihanna got the word "Breezy" tattooed on her neck. "Breezy" is -- as you all know -- Brown's nickname. "She got it to symbolize her commitment to him. Now the world knows they're back together, they're determined to make it work," a source said.

Right.
