Charlie Sheen is notorious for his wild antics, and now he’s picked a fight with Rihanna. The former “Two and a Half Men” star is lashing out at the pop star after she reportedly brushed him off.

Sheen took his fiancée to dinner at Giorgio Baldi in L.A. last night to celebrate her birthday. Rihanna happened to be at the restaurant, but when he tried to arrange a meeting, he was told it would not be possible due to the amount of paparazzi waiting outside.

But Charlie did not take lightly to the rejection. He blasted Rihanna on Twitter, claiming that he “couldn’t pick her out of a line-up at gunpoint.”

“No biggie for me; it would have been 84 interminable seconds of chugging Draino and ‘please kill me now’ that I’d never get back,” he said. “Sorry we’re not KOOL enough to warrant a blessing from the Princess. (or in this case
the Village idiot).”

He also called her a “big ol liar” and criticized her pink hair (“Halloween isn’t for a while”).

“See ya on the way down, (we always do) and actually, it was a pleasure NOT meeting you,” he said. “I’m guessing you needed those precious 84 seconds to situate that bad wig before you left the restaurant.”

He also had some advice for her. “If ya don’t wanna get bothered DONT LEAVE YOUR HOUSE! and if this ‘Prison of Fame’ is soooooooo unnerving and difficult, then QUIT, junior!” he said.

But Rihanna claims she did not even know that Sheen was at the restaurant. “To think that I went there to have dinner in peace like I ALWAYS DO!” she told a fan. “Not once did anyone ask to meet me or take pix, I didn’t even know this old man was in there!”

She also addressed the incident on Twitter. “If that old queen don’t get ha diapers out of a bunch…” she said, telling one fan, “dat nigga recognized me in a wig bruh!!! Haa.”

Sheen fired back at RiRi via TMZ after the “queen” comment. “Firstly I want to thank you for recognizing me as Royalty. I’m flattered,” he said. “And secondly; do the good Queen a favor and go tend to the dungeon in my Castle.”
