Though Kylie Jenner turns 20 years old later this month, she's finally going to high school prom.

Fans will remember that both Kylie and BFF Jordyn Woods attended Rio Americano High School's prom in Sacramento, California, in April, and now viewers of her new reality docu-series, Life of Kylie (which premieres on E! this Sunday, August 6), get a behind-the-scenes look at how she got ready for the dance.

In a preview for the season premiere of the new show, Kylie tries on a couple of dresses (and nixes one that she says is "too boob-y" for her date, the very lucky Alberto Ochoa) and looks at pictures of her assistant, Victoria Villarroel, at her own prom. When Victoria asks why Kylie never went to prom when she was a teen, the reality star/beauty mogul explains that she was homeschooled, so she never had the chance.

Ky then goes on to say that she was really sad she missed out on the event and even unfollowed her old friends from school on social media because seeing all their prom pics upset her. She says in the clip, "They probably all thought I hated them — but I just couldn’t see it. They would post photos and they were all at the prom and I was, like, 'I can’t see it.' It really just made me sad."

But Kylie finally gets her chance to dance to the "Cha-Cha Slide" just like the rest of us — although her rose gold gown is definitely much fancier than anything we wore to our proms. We already know that Alberto's classmates were shook when he showed up with Kylie Jenner, so we can't wait to see more from what was surely the prom of the century.

Watch the trailer, below.
