RiRi slams Charlie Sheen over 'get your diapers out of a bunch' Twitter rant

Rihanna was seen making a fightback after Charlie Sheen slammed her on Twitter.

The Barbadian singer wrote on her Twitter account "if that old queen didn't get ha diapers out of a bunch," The New York Daily News reported.

The Twitter war was started after Sheen told his 11 million followers that Rihanna refused to meet his bride-to-be, Brett Rossi, while they were all dining at the same restaurant on Rossi's birthday.

The Barbadian singer poked fun at Sheen's Twitter rant by changing her Twitter background image to a Photoshopped image of Sheen getting an autograph from her.
