Rihanna goes from blonde to black

Los Angeles: Rihanna has once again reinvented her looks by changing her hair colour - the singer has changed her blonde locks to a darker shade.

Aceshowbiz.com reports that the 24-year-old posted photos on Twitter, sporting jet black hair in three different poses and the caption said: "Cuz I'm black b***h."

When a fan pointed out that her new look was similar to her previous Mohawk style, she replied: "I was missing she, but I aint ready to chop ha."
