“American Idol” runner-up Katharine McPhee has completely changed her hair color and style, going from brunette hair to a bleached blonde described as a rocker style new look to promote her latest album “Unbroken”, which hits stores October 6.

“I’ve never dyed my hair before so this was a pretty drastic change,” Katharine said. “I’ve always been known as a brunette but I’ve been thinking about it for a long time and it kind of just fit with all of the searching with the music and experimenting that I would do the same thing with my look.”

The 25 year-old singer/songwriter revealed her new look matches her music, which has become edgier when compared to her self-titled debut album (2007): “My music is a little more edgy so that inspired me to be adventurous.”
