It's not her sculpted rear, Wii thighs (check out trend below) or killer cleavage -- what makes Jessica Alba hot, according to scientists, is all in the way she walks.
It's not good enough to say someone has sex appeal, that they're aesthetically appealing or just darn good looking anymore. Over at Cambridge, they needed a scientific explanation for why certain celebrities are considered more attractive than others, and it turns out, when it comes to Ms. Alba, it all boils down to her strut.
"The academics found that it is the ratio between hips and waist that puts the sway into a woman's walk - and the nearer that ratio is to 0.7, the better," the Telegraph reported. "This ratio provides the body with the right torso strength to produce a more angular swing and bounce to the hips during the walking motion."
"Therefore, a woman with a 25in waist and 36in hips would have just the right proportions to carry off a sexy swagger as she walks. The Jessica Alba sashay beat off competition from Kate Moss, Angelina Jolie and even Marilyn Monroe, whose walk along a railway platform in Some Like It Hot is one of the most famous in film history."
"While Monroe was a fraction off the target ratio with 0.69, the Cambridge team said that Alba had the perfect proportions."
The woman certainly can dance too; check out the video below.
