Kellie Pickler Shaves Her Head

Killie Pickler the country star buzzed off her blonde locks on Tuesday in support of her best friend, Summer Holt Miller, 36, who is diagnosed with breast cancer.

“Cancer does not discriminate,” Pickler said in a release. Added Miller, “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.”
