The evening, which is held in conjunction with Women Rock for the Cure, honors those who have overcome breast cancer, and those who are still battling it. In addition to Kellie, Sarah Darling, Little Jimmy Dickens, Kristen Kelly, the Farm and Mindy Smith were all on hand to perform.
The "Tough" singer has always been active when it comes to breast cancer awareness, most recently taking it to the extreme by shaving her head last month. Kellie joined her childhood friend, Summer Holt Miller, who is currently fighting breast cancer, in lopping off her locks.
"Cancer does not discriminate," the country singer explained. "If this compels even one person to change their mentality toward waiting until the age of 40 for their mammogram," Summer added, "then it will be worth it."
Fans can catch Kellie on the road next week. She performs on Nov. 7 in Morresville, N.C. Find more of her tour dates here.
