Momager Kris Jenner shared the video, explaining how proud she is of her daughter for bravely opening up.
"When I was 14 I couldn't reach as many people as I can now," Kendall says to the camera.
"Now that I’m 22 and I have this whole thing behind me I can, I can speak to so many people and just be like, I can help you and its okay and I experience it, I’m very normal," the model said. "And like, I understand you. Like, I can connect with you."
So what was it all about?!
Fans speculated that it could be about her anxiety, or maybe even that she was coming out as bisexual... but they were so wrong.
It comes at an interesting time though, as today is the Golden Globes in America. If you cast your memory back to the Golden Globes last year, it was when Kendall stepped out with acne on her face and was commended for it.
