(CNN) — Everyone has their own ways of showing support for a loved one facing a cancer diagnosis, and for Kellie Pickler, it meant standing in hairstyle solidarity.

In a video she submitted to “Good Morning America,” the “American Idol” alum and her best friend, Summer Miller, shaved off their hair in preparation for Miller’s chemotherapy treatment, which is scheduled to begin Thursday.

Miller, whom Pickler refers to as her “sister,” was diagnosed with breast cancer in June.

Miller’s just 35, but as Pickler says in her statement to ABC News, “cancer does not discriminate,” and it’s important to aim for early detection.

“If this compels even one person to change their mentality toward waiting until the age of 40 for their mammogram, then it will be well worth it,” Pickler added.

And with her new buzz cut, it looks like Pickler has a Halloween costume already in the bag: “Thinking about being ‘G.I. Jane’ for Halloween,” she tweeted with a wink on Wednesday.
