Kylie Jenner's new documentary/reality series Life of Kylie is getting a two-part premiere on Sunday, but fans can already glimpse one of the show's most revealing moments.

A big chunk of the first episodes focuses on Jenner accompanying an unsuspecting fan named Albert to prom. In a new clip released by E! News, Jenner is shown trying on dresses for the occasion, some of which show a bit too much skin.

"It's a little booby for me and Albert, you know?" she quips at one point.

After her assistant shows off her own throwback prom photos, Jenner's asked why she never went to prom when she was in high school. In what's one of Life of Kylie's most genuine moments, Jenner says she had to be home-schooled due to her growing fame.

She was apparently so disappointed she couldn't accompany her previous classmates to the prom that she unfollowed her friends on social media to avoid seeing all the photos from the celebration.

"It was really sad actually," she said. "I had to un-follow all my friends that I went to school with. They probably all thought I hated them but I just couldn't see it, you know, because they would always post photos and they were all at the prom and I was like, 'Can't see it.' It really just made me sad."

E!'s Life of Kylie premieres Sunday at 8 p.m. CT.
