E!'s Ground Zero for Rihanna-Ciara Twitter Smackdown

On this episode of Twitter smackdown, it's Ri-Ri vs. Ci-Ci.The two singing divas (and former Chris Brown lovers) went at it yesterday after Ciara brought up Rihanna on our very own Fashion Police. "I ran into her recently at a party. She wasn't the nicest," Ciara told the Joan Rivers-led panel. "It's crazy, because I've always loved and respected what she's done in fashion. It wasn't the most pleasant run-in."Well, Ri-Ri wasn't too pleased.She tweeted: "My bad Ci, did I forget to tip you How rude of me....You gangsta huh Ha."And so it began!Ciara came back with: "Trust me Rihanna you don't want to see me on or off the stage.""Good luck with bookin that stage you speak of," Rihanna tweeted. Ouch!But apparently Ciara found that funny, replying with: "Pure comedy."It didn't stop there! The biggest diva of them all, Perez Hilton, decided to join in, backing up Rihanna.He tweets: "@ciara It obviously wasn't funny to her. It was hurtful. @Rihanna has had a difficult week.""@ciara And I'm sure your week has been difficult too, publicly proclaiming that your label doesn't support you and you want to be dropped."Dang!Eventually the beef became too much, and Ri-Ri decided to make amends."Ciara baby, I love you girl!" she tweeted. "You hurt my feelings real bad on TV! I'm heartbroken! That's why I retaliated this way! So sorry! Let's make up."Perez chimes in: "@ciara She extended an olive branch to you now and is being the bigger person. Accept it and move on. Or stay petty and less successful."What else could Ciara do but reply with: "Ri, u know its always been love since day 1! Doing shows and everything. You threw me off in that party! Apology accepted. Let's chat in person."Awww-all is good in the Twitter world again.Of course, Perez was happy with the outcome too."@ciara Good! #LoveAndLight Now if only @NICKIMINAJ and @LilKim could make peace too!"Yeah, somebody would get a Nobel if that came to pass.
