Kim Kardashian faces constant scrutiny on social media, but she admits that she holds back when it comes to clapping back ... until she hits her breaking point.

In a new video on her website and app, the "Keeping Up With the Kardashians" star admits that she takes on her haters "when she feels like someone is being really fake."

"I personally take the high road most of the time," she tells BFF Jonathan Cheban in the clip. "I always think, 'Will I be affected by this tomorrow? In a week? In a month? In a year?' Usually the answer is no."

Mrs. West adds that she claps back to feel better about the situation. "If you feel like talking s--t to someone, go for it," she declares.

She even touches on her Twitter feud with Bette Midler, who criticized Kim for posting that infamous nude pic.

"She was such a legend," Kardashian says. "She's such a legend that you don't want to say anything disgraceful to her and to you," Cheban chimes in.

Kim has one last comment for the music icon: "You do you, and let me be me. No need to be rude or tear someone else down."

The reality star also takes on body-shamers who have claimed that she got liposuction to lose weight.

"I'll just be like, 'You have no idea how hard it is for me to do low carbs and to really focus,'" she explains. "I spend so much time and energy working out, getting up at 6 a.m., and making sure I do it before the kids are up. That's something that pisses me off."
