What Was Said: In May, Charlie Sheen kicked things off by posting one of his infamous "Twitter poems" about an alleged negative encounter he had with the singer. Apparently, Charlie had asked Rihanna to meet him and his fiancée, who was celebrating her birthday. When Rihanna's team said that the meeting wouldn't be possible because of photographers, Charlie was not pleased. He wrote: "Sorry we're not KOOL enough to warrant a blessing from the Princess (or in this case, the village idiot)." Charlie added, "Here's a tip from a real vet of this terrain; If ya don't wanna get bothered, DON'T LEAVE YOUR HOUSE!"
How Ri Responded: While never naming Charlie outright, Rihanna referenced the actor's rant on Twitter, writing, "If that old queen don't get ha diapers out of a bunch." She also changed her Twitter header photo to a Photoshop of herself signing autographs for Charlie. The actor later responded by saying that "clearly English is NOT your primary language" and called her a "doosh."
