Official: Kylie's perfect bum

It is something many have suspected all along but now it is official - Kylie Minogue really does have the perfect bottom.

And it is all down to her waist-to-hips ratio of 0.7, according to scientists who have spent years studying her form.

The curve of a woman's waist and hips is attractive to men if the waist measures exactly seven-tenths of the bottom.

Not only is it a sexual attraction but it also represents the most suitable body for reproduction.

Of course, some men prefer their female derrieres to be more Jennifer Lopez than Kylie. But, according to Prof John Manning-from the University of Central Lancashire, Kylie's is just right.

He said: 'The bottom is a general sign of a woman's level of sex hormones in her body and her general health.

'It's her fat that is the key. Women tend to lay down fat on their bottom and thighs, which forms a reserve for pregnancy, hence the reason men are subconsciously attracted to this shape. It's a clear sign the female can reproduce.'
