Kellie Pickler debuted a shaved head on Good Morning America this morning, and she said it was to support her best friend, Summer, who was just diagnosed with breast cancer. Since then, diehard fans and new admirers of the country singer have Tweeted their support. "You look even more beautiful," Ellen DeGeneres wrote. Moved, Pickler replied to everyone, "I cannot thank everyone enough for all the love and support you've given Summer. Chemo starts tomorrow. #SayAPrayerForSummer" What a huge heart! We love that she took on such a bold new look to honor her friend, and we're curious: Would you ever shave your head for someone you love? Tell us in the poll!
