Country cutie Kellie Pickler has taken the plunge to show support of her childhood best friend who is a cancer survivor by shaving off all of her hai.

The former “American Idol” star stood by childhood friend Summer Holt Miller, who she affectionately calls her “sister” throughout her breast cancer prognosis and her treatment. But yesterday, the duo took steps to raise awareness for the importance of early detection by shaving off all of their hair.

Miller, who was just 36 when she was diagnosed, joined Picker on ABC’s “Good Morning America” Tuesday to reveal their new look.

“Cancer does not discriminate,” Pickler 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,” Miller said.

Miller’s family had a history of breast cancer and as so, requested a mammogram from her doctor. And it was a decision that saved he rlife, as the the tumor could have turned fatal had it not been caught early.
