Khloé Kardashian came to Kim Kardashian's defense after a fan body-shamed her online.

It started after she shared this pic on Instagram yesterday of herself in a sheer white dress. "WOW, WOW, WOW," Kim wrote in the comments, leading one fan to @ Kim and say, "Hey Pamper booty."

Khloé then slid in the comments and wrote back: "Hey, blocked brows."

Another person then tried to defend the fan by saying that they'd "rather have blocked brows that's easy [to take] off than a saggy diaper," which Khloé also called out.

"Those things are tatted on, but a hater is going to hate," she said. "That ass is ass'n but you do you baby, that's why we have so many flavors. Not everyone has the same taste. Sending you love and a little bit of agua. You seem thirsty, my love."

In the comments, people praised her for how she stood up for her sister.

"Get her!" one person wrote. "You and your whole ass look [is] phenomenal."

Another fan agreed that Khloé looked "gorgeous" and said that her response might "be the best clapback" they've ever seen.

"I fiercely protect my sister, too."
