The stars are switching up their looks this spring. Chris Brown bleached his hair blonde then went back to black, Keri Hilson let her blonde hair down, and Chrisette Michele opted for a curly ‘do.

Now Jessie J has also felt the need for change, debuting longer locks at the Teenage Cancer Trust concert on Sunday. The “Price Tag” songstress, who turned 23 over the weekend, wore her jet black hair in a ponytail, along with overalls, houndstooth stockings, and ruby red shoes. She is gearing up for the stateside release of her debut album Who You Are on April 12.
