Celebrities across the world Tweet and Facebook their support for Angelina Jolie today for her brave decision to undergo a double mastectomy due to her extremely high risk of developing breast cancer. While reading all of the messages of love and care, we were reminded of another story not long ago of beautiful support in the face of the of this terrible disease.

Last year, when former American Idol finalist and current Dancing With the Stars 2013 contestant Kellie Pickler encouraged fans to tune in to an episode of Good Morning America, we weren’t sure what she had up her sleeve. Turns out, she was about to come out in support of a friend with breast cancer in a big way.

The American Idol beauty shocked viewers by shaving her head alongside her best friend Summer Miller, who’s being treated for breast cancer. The singer pulled the dramatic stunt as a show of support for her pal and as a way to encourage early detection for others.

Kellie said in a statement, “Cancer does not discriminate … 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.”

She shared a video of herself and Summer getting their hair buzzed off and joked on Twitter that with her new look, she’s might dress up as G.I. Jane for Halloween!

Back in March, Kellie Pickler told CMT Radio that Summer is "doing great" and she is "overwhelmed at the support she's been given from all over the world."

Watch the video of Kellie getting her drastic makeover below.
