The divas duked it out on Friday night as Ciara and Rihanna got into a feisty Twitter exchange that had the Internet buzzing.

CiCi appeared as a guest judge on E!’s “Fashion Police” earlier in the evening. When a photo of Rihanna at the BRIT Awards was shown on screen, she commented,

“I ran into her recently at a party and she wasn’t the nicest and it’s crazy because I’ve always loved and respected what she’s done with fashion. I’ve ran into her before, but this time it wasn’t the most pleasant run-in.”

Host Joan Rivers chimed in by saying, “A bitch!” before Ciara told her with a laugh, “You crazy.”

Rihanna was tuned in to the television because she responded on Twitter shortly after the episode aired.

“My bad ci, did I 4get to tip u? #howrudeofme,” she wrote before Ciara shot back, “Trust me Rhianna u dont want to see me on or off the stage.”

“U gangsta huh? Haaa,” laughed the “S&M” singer. “Good luck with bookin that stage u speak of.”

But the ladies settled their differences soon after.

“Ciara baby, I love u girl! U hurt my feelings real bad on TV! I’m heartbroken! That’s y I retaliated this way! So sorry! #letsmakeup,” said RiRi.

Ciara agreed to put it behind them, telling her peer,

“Rhi u know its always been love since day 1! Doing shows/everything. you threw me off in that party! Apology accepted. Let’s chat in person.”
