And speaking of pianists, fellow keys player Christina Perri also posted a picture of herself without makeup, giving her fans a glimpse of what she looks like without all of the eyeliner and lipstick. 

Unlike most of the pictures in this list, Perri's makeup-free photo is a much more raw, posed image that evokes a lot of different feelings upon viewing. She looks vulnerable showing her naked shoulders and face, and her shadowy, blank expression makes her look lost or like she's blending into the stark white background.

We have to give Perri major props for this artistic shot, and for showing off her au natural mug to the world.
