Last week she went "gangsta gothic geisha" for her latest music video, and now Rihanna is debuting yet another dramatic new look.

The "Princess of China" singer, 24, showed off long, jet black hair while promoting Battleship in Tokyo Monday. And while the color and style appeared rather tame for Rihanna, she also shaved a section above her ear on one side. See more pics of the singer's 'do.

"I was missing she, but I aint ready to chop ha," she wrote on Twitter in response to a fan who pointed out that the daring 'do looked like one she had before.

A few days before making the drastic change, Rihanna rocked her long blonde hair with a colorful patterned Stella McCartney jacket, which she wore as a minidress in London.
