Daaum! Fei Fei Sun is going with her bad self! Above, pictures from the December issue of ELLE China - plus the cover of course. Fei Fei's naturally a regular at ELLE China: this marks her second cover for the magazine... and it's only been a few months since Fei Fei's Vogue China cover... and her Harper's Bazaar China cover. What's 'rock on' in Chinese?
