Washington, Sept 21 (ANI): Talk show host Ellen DeGeneres is taking classes on walking from actress Jessica Alba, after learning that the latter has the sexiest strut.

A British study said that Alba has the sexiest walk, using mathematical calculations.

The study used ratio between the actress' hip and waist, reports Contactmusic.

Experts from the Cambridge University said that 'the right torso strength to produce a regular swing and bounce to the hips during the walking motion."

"Therefore a woman with a 25-inch (63.5 cenitmetres) waist, and 36-inch (91.4 centimetres) hips would have just the right proportions to carry out a sexy swagger as she walks," they added.

When the actress made an appearance on the Ellen DeGeneres show recently, the host asked Alba to teach her how to walk.

An embarrassed Alba, who called the study silly, reluctantly agreed and took a walk with DeGeneres saying 'I don't understand'. (ANI)
