Rihanna has a bangin' new 'do!

At the 2011 Jingle Bell Ball in London Saturday, the "We Found Love" singer traded her mane of brunette curls for a blonde rounded crop with full, blunt bangs.

No word if the 23-year-old star was wearing a wig for her on-stage act or if we'll be seeing her as a blonde again, but it is refreshing to see her switch up her style. (She also rocks a platinum blonde wig in her new campaign for Giorgio Armani Jeans.)

Rihanna's BFF Katy Perry also stepped out with a brand-new 'do this weekend. The singer lopped off her locks into a chin-length cut, which she debuted in L.A. Saturday.

The Barbados-born beauty, who's as well known for her chart-topping hits as she is for her dramatic hair changes, dyed her hair a fire engine red and shaved off the sides of her hair in June 2010. She spent some time with her crimson locks and in the late summer, ditched the eye-popping color for a sun-kissed brunette.
