You can't beat a good arse. Given that today is National Ass Day, we thought it was high time we took a look at some of the most celebrated derierres in 'slebville. While we're taking it to refer to people's rear ends, you could argue also that it's a day for celebrating people of the asshole variety. Hence the inclusion of Mel Gibson on this list.

Girls with pert posteriors are ten a penny - see Beyonce, JLO, Kim Kardashian and more - finding a worthy celebrity male with a good tush, however, proves more challenging. Of all the men we've researched, we reckon Daniel Craig as James Bond deserves the top prize here. Just look at it. *imaginarysqueeze*.

Without further ado, given that asses are there to be ogled rather than spoken about, let's take a gander at the best buns in the business. Agree? Disagree? Anyone you'd care to add? Tell us!

Oh and before we go, Happy National Ass Day!
