Charlie Sheen has replied Rihanna after she changed her main twitter image to a pic of him asking for her autograph & called him an 'old queen with his diapers out of a bunch' (read here). Charlie writes:-
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"
