When you watch porn, we’re sure the first thing that comes to your mind is: “Gee, I wonder what that girl looks like without make-up?”

Well, wonder no more … because a woman named Melissa Murphy — makeup artist to the porn stars — has released a ton of before and after shots of female adult entertainers showing how her skills transform these women from regular ol’ Plain Janes into camera-ready sex kittens.

The photos Murphy posted to her Instagram over the weekend show nearly 100 different porn stars in their various stages of beauty — depending on what you perceive as “beautiful” of course.

In an interview with the Huffington Post earlier today, Murphy — who has been a makeup artist for eight years — says that she never expected her pictures would become a viral sensation. A post showing them on the photo sharing site imgur has been seen by nearly 1 million people in just 3 days!

“I am grateful to all the models who have allowed me [to use their photos],” she told HuffPost.
