You've seen them without their clothes -- now see them without makeup.

Dozens of adult actresses and nude models truly bare it all in this amazing before-and-after photo series by Melissa Murphy, makeup artist to the (porn) stars.

Murphy, who has been a makeup artist for eight years, says there's not a huge difference between doing makeup for adult film actresses and for brides on their wedding day.

"If you're going to make a woman beautiful," she told HuffPost Weird News, "you're just going to make the woman beautiful."

A makeup artist on a porn set needs to be extra careful that everything is going to stay in place, but Murphy, 35, pointed out that she would do this anyway.

She began posting before-and-after photos on instagram a few months ago, and says she never expected the images to become an overnight viral sensation. "I am grateful to all the models who have allowed me [to use their photos]," she told HuffPost.

So which porn stars make the best makeup clients?

"Joanna Angel," Murphy told HuffPost, is "one of my favorites … She gives me a lot of creative control and she works on really interesting things … she pushes me to do things I've never done before."

Murphy isn't the only one who loves Joanna Angel. In January, intrepid HuffPost Weird News reporter Andy Campbell found out she makes a great date.
