In 2011 the Rear of the Year award (which is a genuine award in the UK) should have gone to Pippa Middleton. Sadly she lost out to Carol Voderman but it didn't stop Middleton's bum from being the most talked about bottom of the year.

We're not sure what it was but the country seemed to fall far more in love with Middleton's behind than her sister Kate's lavish dress, the elegant carriage and the general pomp and ceremony which comes with any royal wedding. Nevertheless, a large proportion of the populace was simply obsessed with Middleton's derrière. 

This year it appears Kim Kardashian has made a bid to have the most discussed bum of 2014 with her 'Break the Internet' cover for Paper magazine. The photo shoot received mixed reviews with some celebrities praising Kardashian for her brazen shoot whilst others condemned it. 

31-year-old Middleton, writing in the Spectator, appears to have been impressed with Kardashian's backside but also disturbed by the "obsession" with it. Middleton wrote: "No year is complete without a bottom story, and the 'Rear of 2014' award undoubtedly goes to Kim Kardashian, after her posterior exploded all over the internet last month."

"I must say that mine - though it has enjoyed fleeting fame - is not comparable. But the Kim butt story did make me pause. What is it with this American booty culture? It seems to me to be a form of obsession. Kim's aim, apparently, was to break the internet, but I'm not sure she's going the right way about it," Middleton concluded. 

Although Middleton may have been slightly critical of Kardashian, Kardashian certainly isn't harbouring any harsh feelings in return. In fact, when asked about Middleton by E!, the 33-year-old reality star simply said "I love her. She has an amazing body. She's beautiful."

At least Kardashian knows how to turn the other cheek...
