Kourtney Kardashian Is on a Mission to Make Her Butt As Big As Khloe's

Kourtney Kardashian

Judging by her Instagram post this morning, Kourtney Kardashian is feeling really left out of the growing battle for best booty among her sisters. But the proud mama of three isn't about to sit on her tush and give up.


Outfitted in monochromatic workout gear, Kourtney posted this pic with a message for her little sister, Khloe, and basically came right out and admitted that she has a serious case of butt envy.

This seems more like a declaration of admiration than fighting words, but either way, Khloe ought to watch her back ... literally!

Kourtney has been extremely vocal about the hard work she's putting in to get her pre-baby body back, having given birth to third baby Reign in December. She looks incredibly fit, and I certainly can't criticize a woman for wanting to be healthy for her kiddos -- parenting takes stamina! She may be shrinking in other areas of her body but wants to ramp up her booty, and who can blame her?

While Kim long held the title as the most apple-bottomed of the Kardashian girls, Khloe's bum has been giving Kim's a run for its money lately. It sure sounds like Kourtney is ready to throw her hat into the competition ring too. But having always been the most petite of the family, Kourt is going to have to put in some serious time towards glute exercises to compete with her sisters. She might want to throw in an extra set of squats each day just for good measure.
