Grammy-winning singer Rihanna is throwing more shade into the face of Hollywood stud Charlie Sheen after turning into the victim of a full-fledged Twitter attack. #Winning

Following Sheen’s explosive shots, RiRi embraced some paparazzo opportunities in California.

Rihanna showed up at Giorgio Baldi in Santa Monica Thursday … knowing photogs would ask about the war of words between Charlie and her … ignited after she refused to interact with him and his fiancee during dinner. In what can be interpreted as an F-you to Sheen, Rihanna got all friendly with gawkers as she walked in … but ignored questions about Charlie. (TMZ)

Along with posting responses in the form of TwitPics, RiRi also clowned Sheen by switching up her Twitter profile background this week.

The Anger Management star called the singer out for being rude to his fiancé at a restaurant Wednesday night — so Rihanna knew she had to come up with something good. Cue the HIGHlarious set of tweets. To top this feud fabulocity off, Ri changed her profile background image to a silly photoshopped picture of Charlie’s head on a small body, while she’s signing an autograph! You can see that (above)! So many LOLz, so little time! Mr. Sheen hasn’t responded to the shade quite yet…but we’re sure he’ll come around! (Perez Hilton)

RiRi appeared to initially respond to the rant with a couple short remarks yesterday (May 22).

“Goooorrrrrrlllllll……,” Rihanna wrote May 22.

“If that old queen don’t get ha diapers out of a bunch…” (Rihanna’s Twitter)

Charlie posted his epic rant toward RiRi on Twitter.

“so, I took my gal out to dinner last night with her best friends for her Bday. we heard Rihanna was present as well. I sent a request over to her table to introduce my fiancé Scotty to her, as she is a huge fan. (personally I couldn’t pick her out of a line-up at gunpoint) well, the word we received back was that there were too many paps outside and it just wasn’t possible at this time. At this time? AT THIS TIME?? lemme guess, we’re to reschedule another random 11 million to 1 encounter with her some other night…?” (Charlie Sheen’s Twitter)

Sheen proceeded to unload his issues toward RiRi after revealing how upset his fiancée became.

“oh and Riahnna, Halloween isn’t for a while. but good on you for testing out your costume in public. it’s close; a more muted pink might be the answer, as in: none. See ya on the way down, (we always do) and actually, it was a pleasure NOT meeting you. clearly we have NOTHING in common when it comes to respect for those who’ve gone before you. I’m guessing you needed those precious 84 seconds to situate that bad wig before you left the restaurant.” (Charlie Sheen’s Twitter)
