You would think an A-list celebrity like Charlie Sheen would understand another celebrity, just wanting a private moment, right?

Well, apparently Charlie’s so use to getting what he wants he had to let Rihanna know exactly how he felt about her refusal to meet his fiancée, Wednesday night at the upscale Giorgio Baldi restaurant in Santa Monica.

Charlie and his fiancée, Scottine were there to celebrate her birthday.  She’s a huge Rihanna fan so when she found out the singer was there, she had Charlie send over a request to meet her.

Well, RI RI wasn’t in the mood so the request was denied!

Sheen took to twitter writing,

“Nice impression you left behind, Bday or not.  Sorry we’re not KOOL enough to warrant a blessing from the Princess (or in this case the Village idiot).”

And then the personal attacks Charlie is known for commenced.

“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.”

Rihanna not one to bite her tongue returned fire tweeting,

“If that old queen don’t get ha diapers out of a bunch…”

To which Charlie responded:

“Dear Ms. Rihan-
oh wait, no last name,
Okay, Dear R –
clearly English is NOT
your primary language.

Firstly I want to thank you for recognizing me as Royalty. I’m flattered.
And secondly;
do the good Queen a favor and go tend to the dungeon in my Castle.
But beware of the
rats and the snakes.
They stir with folly
awaiting your tepid advance,
in the shadows…”

later Doosh!
cs”

This is all such silly nonsense!

Rihanna now says she didn’t know Charlie was in the restaurant.  But even so, isn’t she allowed to have a private dinner?

Let me know your thoughts.
