One Day, Two OMG Booties! Khloe & Kim Kardashian Face Off In L.A. Booty Battle – See Who Has The Bigger Butt In 10 Photos

It's a booty battle! Khloe Kardashian showed off her curves in her yoga pants just hours sister Kim Kardashian dared to bare in white, and RadarOnline.com has a gallery of their feuding booties.

Khloe showed off her new braids — and curves! — as she arrived at a Los Angeles gym for a major workout session on April 30.

But it was her banging booty that stood out as she bent over and leaned into her car.

Khloe's pin-thin legs made her big butt look even more pronounced as she pranced into the gym in a pair of tight yoga pants.

Even from the side Khloe, 30, rocked her round rump.

No parking tickets for Khloe, but that booty should be illegal!

Still Mrs. Lamar Odom, the pretty brunette packed a lot of junk in her trunk.

The Keeping Up With the Kardashians star is dedicated to staying shape but still maintaining her diabolic derriere.

The youngest Kardashian sister is blessed with the same genetics as her older sisters and she flaunted her curvy figure in her all black Nike workout clothes.

Her older sister Kim, 34, has a banging butt too and could give her sister some tough competition in the booty battle.

So how does Khloe's booty compare to Kim's white hot bottom? Sound off in comments below.
