Pippa Middleton has admitted her butt is "not comparable" to Kim Kardashian West's derriere.
The sister of the Duchess of Cambridge - whose posterior shot to fame when she wore a tight-fitting bridesmaids dress at Duchess Catherine and Prince William's wedding in 2011 - insists her backside is not in the same league as the US reality TV star's and has tipped her to be crowned Rear of the Year.
In an article written for political weekly magazine The Spectator, Pippa explains: "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."
Her comments come after Kim posed naked and covered in baby oil for Paper magazine last month, including one shot in which she had a champagne glass perched on her posterior, in an attempt to "break the internet", but Pippa thinks there are better campaigns the 34-year-old stunner could have tried out.
The 31-year-old brunette wrote: "Kim's aim, apparently, was to break the internet, but I'm not sure she's going the right way about it.
But Pippa - whose sister, Catherine, has 16-month-old son Prince George - did beat Kim to one award this year as in July she was crowned Auntie of the Year, beating off strong competition from the 'Keeping Up with the Kardashians' star, Victoria Beckham and Beyonce Knowles.
