What a difference a few days makes!

Rihanna showed off a much darker new 'do today at a press conference for "Battleship" in Japan -- just days after promoting the movie as a blonde in London.

Not only was she rocking black locks, but the side of her head was also shaved.

It's definitely a more edgy look for the singer, who was both blonde and a red head in the past year.
