How far would you go to support a friend? Country star/American idol alum Kellie Pickler has shaved off her blond locks as a show of support for her best friend, who was diagnosed with breast cancer.

35-year-old Summer Holt-Miller and Pickler have been friends since childhood, and in anticipation of beginning chemotherapy this week, shaved her head. Pickler, who considers Miller a 'sister', showed her solidarity by shaving off her own hair. She submitted the video (below) to Good Morning America.

Miller, whose personal story can be read here, is the mother of two young children, and said, "If this compels even one person to change their mentality toward waiting until the age of 40 for their mammogram, then it will be worth it."
