Rihanna is looking glam and gorgeous as a geisha on the set of her music video for "Princess of China" ... her duet with Coldplay!

In these new Twitter photos, the 24-year-old songstress used chopsticks and wicked makeup to complete her look. RiRi Tweeted, "Gangsta goth geisha #thuglife #princessofchina."

Gotta love how Rihanna is utilizing her extra long nails. Diva-licious!
