"I wore this wig many years ago to the American Music Awards just for fun to change it up," she wrote on Instagram. "But now since my mom has lost her hair from cancer treatment, I felt like what better time to dust it off and have a little fun?? Here’s me teaching my mom to give a good soap turn-hair flip."
