Rihanna And Ciara Engage In Twitter War Of Words! (PHOTOS)

What a mess one statement can make.

Ciara ignited a war of words with Rihanna when she appeared on E!’s Fashion Police to rip on red carpet looks , and, apparently, air out some dirty laundry on the pop star.

“I ran into her recently at a party and she wasn’t the nicest,” CiCi 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 just wasn’t the most pleasant run in.”

The comment obviously peeved RiRi off, causing the pop princess to take to Twitter to issue a scathing comeback. “My bad ci, did I 4get to tip u? #howrudeofme” Ouch!
