ZOO is the magazine of the people.

We always want to see what you're up to (not in a weird, stalker-y way). We always want you to get involved in the mag where possible. And right now, we want to know your thoughts on the biggest issue gripping us all right now.

No, not the worries about a second recession. Yep, you guessed it: we want to know which girls you think have the world's best bottoms.

We want to round-up the Top 50 Favourite Arses In The World, and seeing as there are so many to choose from, we want your help in narrowing them all down.

There's Kylie Minogue, who's been known for her cute behind since before Harold went a bit crazy on Neighbours. Jennifer Lopez is often described as the ultimate for those who prefer a bigger booty, and although it's her hips that don't lie, Shakira's arse certainly isn't lying either when it comes to how perfectly rounded it is.

Beyoncé created the word "bootylicious" - so it's no wonder that her bum is pretty damn awesome too. And there's so many more to choose from: ZOO cover star Kim Kardashian, Barbadian singer Rihanna, and super-curvy Hollywood hottie Scarlett Johansson to name but a few.

Oh, and before you ask, the image at the top of this page belongs to Melissa Debling - so remember that you can  nominate your favourite, bum-perfect ZOO girls too! Just use the form below and enter the girls who have the arses you love!
