As you probably already know, that right there is Mia Khalifa. Yes, I’m assuming you’re familiar with the hottest new adult film actress of today because, if you’re reading this, I know two things about you: you have access to the Internet and you have at least one working eye, or possibly both. Therefore, you know Mia Khalifa.

Recently, the Microsoft app How Old has been making waves online, with people testing out the accuracy of the service. Someone thought it would be a genius idea (and they were right, it was) to test How Old on 20 of the most popular adult film stars. For example, Mia Khalifa is 22-years-old. The app, which analyzes the person’s face and guesses their age, predicted that she was 23. Not too shabby. Let’s see how the rest shaped up, compared to their actual ages.
