Ciara and Rihanna
Last year, Ciara commented in an interview that Rihanna had a bad attitude during a recent run-in. The Barbadian beauty didn’t take kindly to Ciara’s comment and launched a Twitter attack that turned into an all-out tweet-for- tweet battle, with Rihanna commenting on Ciara’s career slump and Ciara threatening Rihanna with bodily harm. Shortly afterward, the two patched things up over Twitter, becoming frenemies instead of enemies.
