The sisters hit the red carpet at the NBC Universal Upfronts on Thursday (15 May) to promote their family reality show Keeping Up With The Kardashians.
Curvaceous reality TV star Kim flaunted her boobs in a plunging black dress by Wes Gordon, while Khloe showed off her legs but covered up a little more with a nude camisole under a black wrap dress.
Kim and Khloe posed for plenty of photos together, but as they faced each other, it was their shapely bottoms that got all the attention!
Khloe has been on quite a fitness buzz lately, and as she sized up to sister Kim, she showed exactly why all those hours in the gym have paid off. Her bum is now twice the size of Kim's!
Earlier this month, 29-year-old Khloe showed off her slimmed-down midriff and hourglass physique, after explaining that she had used the controversial waist trainer.
The waist trainer, which is worn under clothes, helps to accentuate the bottom and squeeze in the waist.
The Kardashians are never out of the spotlight, especially when it comes to their famous figures.
Remember when Kim showed off her pert and toned derrière in a bottom selfie posted to Instagram last October? Our jaws dropped when we spotted the candid pic of the 33-year-old showcasing her assets in a tiny white swimsuit!
Bottom selfies - aka 'belfies' - have been a real hit recently, with a whole host of stars getting in on the action. We wonder if Khloe will channel Kim with one too?!
One thing's for certain, Khloe has certainly proved that her big sister Kim's infamous derrière runs in the family!
