Kylie Jenner's life may seem flawless at times, but even she has moments where she feels alone.

"I have a soft spot for the outcast because I was the outcast, I guess, in a lot of ways growing up," she explains. "And I still feel like an outcast in different ways now because I can't relate to a lot of people, so it's like this little world. I do feel like an outcast."
That's why she couldn't be more excited about surprising a young boy, Albert, at his high school prom.
In another scene, Kylie and her BFF, Jordyn Woods, can be seen Facetiming with Albert's mom, who revealed he was "so devastated" and "literally crying" because he couldn't find a girl to go with him.
"He was like, 'What is wrong with me?'" Albert's mom, teary-eyed, continues. "I said, 'I don't know, honey, I don't know.'"
The clip then switches over to a solo interview with Kylie, who explains why she decides to give Albert the surprise of a lifetime.

"Just seeing Albert's mom and the emotion she has for her son, I don't know it's just not cool," Kylie says. "Kids are mean these days and it's not right to treat people like that."
