Bootylicious! Khloe Kardashian wins the battle of the bums as she reveals shapely derriére while comparing figure hugging ensembles with Kim

It may have been the E! upfronts, but for the Kardashians it was all about their backsides in New York on Thursday.

And Khloe appeared to go one better than her sister by revealing a significantly perter derriére than older sister Kim – whose shapely behind serves as something of a trademark. 

The Keeping Up With The Kardashians stars were flaunting their shapely bottoms while posing on the red carpet at the E! upfronts.
