When celebrities have a problem with each other theses days they often take that fight into the Twittersphere.  The current heavyweight fight involved Rihanna and Ciara, both singers take swipes at each other before apparently making peace, all that using only 140 or less at a time. See the fight after the break.

Ciara was a guest on E! Fashion Police and she was talking about an encounter with Rihanna:

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

Rihanna went right to Twitter, saying: "My bad ci, did I 4get to tip u? #howrudeofme (sic)."

Ciara shot back: "Trust me Rhianna u dont want to see me on or off stage," to which Rihanna replied: "U gangsta huh? Haaa. Good luck with bookin that stage u speak of."

Shortly after she tweeted: "Ciara baby, I love u girl! You hurt my feelings real bad on TV! I’m heartbroken! That’s y I retaliated this way! So sorry! #letsmakeup."

Ciara responded: "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."

Well I'm glad they worked that out.
