Most everyone agrees that Shania Twain is a beautiful woman, but a few reseachers say they've actually proven it scientifically. According to the BBC, researchers at the University of Toronto worked out the dimensions of the most attractive female face, and Shania fits the profile perfectly with the correct measurements between her eyes, mouth and ears. She even beat out Angelina Jolie when it came to perfect facial dimensions. 

For the study, researchers asked students to rate the woman's attractiveness in two pictures presented side by side. The only difference in the photographs was the vertical distance between the woman's eyes and mouth and the horizontal distance between her eyes. The findings were published in the journal Vision Research.
