Kim Kardashian West thinks Pippa Middleton ''has an amazing booty.''

The 34-year-old reality TV star is a huge fan of the Duchess of Cambridge's younger sister, who recently insisted her butt was ''not comparable'' to the 'Keeping Up with the Kardashians' star's derriere even though her posterior shot to fame when she wore a tight-fitting dress at Duchess Catherine and Prince William's wedding in 2011.

Asked about the British beauty's comments, Kim told E! News: ''I love her. She has an amazing booty. She's beautiful.''

Pippa, 31, recently insisted her backside was not in the same league as Kim's and tipped her to be crowned Rear of the Year.

In political weekly magazine The Spectator, she wrote: ''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.''

Her comments came after Kim posed naked and covered in baby oil for a magazine last month.

The brunette beauty recently credited her husband, Kanye West, for helping her to feel more body confident, but in an upcoming episode of 'Kourtney & Khloé Take The Hamptons,' Kim admits she is tired of her curves and wants a ''flat a** now.''
