Kim Kardashian Compliments Pippa Middleton's 'Amazing Booty'

Kim Kardashian is in possession of the most famous posterior on the planet, so when it comes to gauging other people's glutes, she's kind of an expert.

That said, Kim finally gave Pippa Middleton a gluteal stamp of approval.

"I love her," Kardashian confirmed to E! News during an appearance at Rihanna's first annual Diamond Ball in Bevery Hills. "She has an amazing booty. She's beautiful."

So what prompted Kim to remark on Middleton's admirable butt? Actually, it turns out Pippa was the one who started it. In her year-end column for The Spectator, Middleton made mention of Kim's hindquarters, dubbing them the "Rear of 2014."

Pippa's comments, however, weren't entirely flattering. After noting that both she and Kardashian have earned cheers for their rears ("mine — though it has enjoyed fleeting fame — is not comparable," wrote Pippa), she claimed to be confused by Kim's nude pictorial for Paper magazine.

"What is it with this American booty culture? It seems to me to be a form of obsession," Middleton wondered. "Kim's aim, apparently, was to 'break the Internet,' but I'm not sure she's going the right way about it."

Nevertheless, both parties seems to ackowledge each other's contribution to keister culture, and isn't that what's really important here?
