Kendall Jenner Photobombs Kim Kardashian's Latest Booty Selfie

Kendall Jenner photobombed Kim Kardashian as she looked to take her latest booty selfie.

Jenner tried to rival her half-sister's famous derriere by showing off her own rear-end as they took a break from working out at a Los Angeles gym on Friday morning.

The 18-year-old decided to upload the photo that showcased her and Kim's bottoms to her Instagram followers. She also added the caption, "Barging in on Kim's booty selfie."

There's no doubting the fact that Jenner posed in a provocative manner for the picture, and the 5 ft. 10 in. model made sure to recreate one of Kim's famous poses.

Unfortunately, her 33-year-old sister was able to use her vast experience shooting "booty selfies" to usurp Kendall, and she made sure that her posterior was the main attraction of the image.

The pair wore tight and clingy Lycra tops to show off their impressive figures to the world, while they also donned tight leggings and trainers for their workout session too.

Kim Kardashian has spent the past few months proving that she has lost the baby weight that she amassed while she was pregnant with her and Kanye West's daughter, Nori West.

In October, she uploaded her first daring selfie while only wearing a white swimsuit, and she added the caption, "#NoFilter," to prove that it was 100% her. It proved to be hugely popular and it even provoked hundreds of copy-cat pictures, while her fiancee, Kanye West, immediately replied by exclaiming, "HEADING HOME NOW."
