Nashville, Tennessee - Miley Cyrus is going through a difficult time right now. The pop star announced the passing of her grandmother Mammie on social media.

Miley (27) posted a moving tribute to her grandmother on Instagram: "Even though you have gone... NOTHING has or will ever change. You will FOREVER be my inspiration and fashion icon."

She added that her grandmother was "a true LIGHT in a dark world" for her. "You are sunshine. Every day I wake and see that fiery ball in the sky I will see your face. Then say a prayer thanking heaven above for giving me the best grandmother a girl could ever be gifted."

"I will miss you for the rest of my life...I will keep your spirit here by continuing to do good for others and treat them the way we all desire to be treated. With an infinite amount of the same gentle kindness you displayed daily."
