But it seems we've changed our minds about what makes a perfect bottom, because Kate's sister is now third place in a recent survey of best behinds, with the gorgeously curvy Kelly Brook taking poll position and Holly Willoughby claiming the runner up spot!
The survey of 2,000 women, conducted by The Original Factory Shop, revealed that 54% of us are happy with our bottom size and shape, hoorah! But who else made the top bottom list?
1. Kelly Brook
2. Holly Willoughby
3. Pippa Middleton
4. Kylie Minogue
6. Cheryl Cole
7. Kim Kardashian
8. Jessica Ennis
9. Kate Middleton
Never one to shy away from a bit of hard work when it comes to her figure, Kelly is a keen exercise enthusiast and often posts pictures of her workouts on her Instagram page. And the results are clear to see! On a recent trip to the beach, the stunning star showed off her famous derriere next to a digitally enlarged picture of her bottom (right) in homage to the infamous selfie (or 'belfie' as its become known) Kim Kardashian took of her own bum, with the caption 'inspired by @kimkardashian'.
Fans, however, were quick to comment that Kelly's perfect the way she is, and we couldn't agree more!
Miss Brook reminds us all that you don't have to be stick thin to look fab. While most of us won't have the time (or money) to spend hours in the gym sculpting our bodies, we're relieved to see that curvy, shapely bums like Kelly's and Holly's are the way forward. Now, if only we could remember to do our squats every morning!
