Rihanna DOES Take Photos with Fans ... In Yo' Face, Charlie Sheen!


may dislike Charlie Sheen ... but she really likes the restaurant where she dissed him Wednesday night ... because she came back the next night and made a spectacle of herself.

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.
