Demi Moore also shocked fans this week, posting an unrecognizable photo of herself in costume as a much-older woman with a bald head and glasses.
According to Moore, the photos were behind-the-scenes snaps from her film \"The Substance,\" in which she plays a former A-lister named Elisabeth Sparkle who is drawn to a mysterious black market drug that promises a younger and more perfect version of herself -- with caveats.
