Khloé Kardashian sings praise for Kendall Jenner for her generous act

Khloé Kardashian is proving to be down-to-earth and relatable, despite her glamorous lifestyle.

On a recent episode of The Kardashians, Khloé was doing a photo shoot for Khloud Protein Popcorn when her sister Kendall Jenner stopped by to show her support.

Khloé, 41, joked that she didn't want Kendall, 30, to watch her because "nobody wants a supermodel watching them."

Kendall, however, was full of praise for her sister, saying she was "killing it" and didn't need any tips. The supermodel also opened up about her admiration for Khloé, saying she's always been the "cool sister" who encourages fun and protection.

The sisters have a strong bond, and Khloé has previously spoken about how much she values her relationship with Kendall and their youngest sister, Kylie Jenner, 28.

In a March episode of Khloé in Wonder Land, Khloé said she despises it when people refer to Kendall and Kylie as her half-sisters, saying "those are my real sisters."

Khloé recently celebrated Kendall's 30th birthday on Instagram, gushing about how proud she is of her sister. "How endlessly proud I am to call you my sister," she wrote. 

"You’ve grown into such a remarkable woman, but you’ll always be my baby."

The Kardashians is a reality series that follows the lives of the Kardashian-Jenner family, and new episodes drop Thursdays on Hulu.
