Cher was on hand at last nights Grammy Awards to introduce good friend Tina Turner's performance with Beyonce.

Backstage the ageless diva opened up on her beauty regimen, joking "I'm a witch! I sold my soul to the devil. I have a portrait of Dorian Grey in my cupboard. I don't know what it is."

She also spoke out on a more serious topic, good friend Farrah Fawcett's cancer battle, saying "She is one tough girl, I couldn't have gone through what she has."
