Rihanna was seen treating herself to an exquisite dinner last night (Thu. Mar 31) at Philippe Chow restaurant in Los Angeles. The “What’s My Name” songbird, who looked gorgeous in a plain white sun dress and flats, was flanked by her bodyguard and a friend outside the popular celebrity eatery.

You can also spot the red-haired beauty on the cover of the April 2011 issue of Rolling Stone Magazine where she talks about Chris Brown, her sexual fantasies and lots more.
