Kellie Pickler Shaves Head in Support of Friend Fighting Cancer [VIDEO]

The buzz today is all about country star Kellie Pickler... literally.  So, why is Kellie sporting a new buzz-cut hairdo?

Kellie's good friend Summer Miller was diagnosed with breast cancer, and is scheduled to start chemotherapy tomorrow.  In a show of solidarity Kellie shaved her golden locks in support of Summer and her struggle to beat the disease.
