It comes as probably the strangest diss in Hollywood History, but Pippa Middleton - sister of Kate, who is married to our very own Prince William - has written a blog post addressing why Americans, and in particular Kim Kardashian, are so fixated on "booty". 

Whilst her sister was visiting New York as part of a Royal visit this week, Pippa was turning her attention to much more frivolous matters. In a blog for The Spectator, which will be published this week, she writes that the "Rear of 2014" award goes to Kim Kardashian after her "posterior exploded all over the Internet".

She even admits that hers "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 writes, breaking the taboo of royalty mixing with celebrity.

Pippa goes on to mention her recent discovery and love of "truffles" in the as yet unpublished blog. It's difficult to believe that such a high class lady wouldn't have discovered this treat often enjoyed by the upper classes, but apparently now that she has she can't get enough, even mentioning that her "flat now smells of truffles!" We'll send our wishes to Pippa and hope she hasn't overdosed on truffles, the poor soul. 

Meanwhile, Kim Kardashian is yet to respond to Middleton's demure criticisms, and we're unsure whether it would be wise to do so. It's fair to say both women are in different social classes, and whilst Pippa's comments on Kim's photo shoot were both fair and written gracefully, would the Kardashian superstar respond in a similar way?  

 Whilst it is arguable that neither female has really propelled themselves to celebrity status, Kim being thrust into the spotlight after a sex tape became public, and Pippa being fortunate enough to come from a wealthy family and be related to the Duchess of Cambridge, we think we know which one would be more respectable to bring home to the parents. #Celebrities
