It was possibly done as a stunt for Life of Kylie, which is why the details are all so vague, but Kylie Jenner hopped a private jet up to Sacramento over the weekend to attend Rio Americano High School's prom, apparently as one kid's date. That kid is high school junior Albert Ochoa, as Mashable tells us, and the buzz on Twitter was that his original date turned him down (allegedly this girl), and somehow he got Kylie to be his date instead.

Ochoa's own sister seemed as confused as anyone:

Earlier Saturday evening Jenner posted the photo above to Snapchat of she and best friend Jordyn Woods on the plane to Sacramento, with no real explanation.

The prom took place starting at 8 p.m. at Tsakopoulos Library Galleria in downtown Sacramento, and he social media eruption over Jenner's appearance began around 10:45 p.m., so I guess she was fashionably late. The folks at the local CBS affiliate are also very confused. But they note that Jenner didn't just make an appearance, she also danced with Ochoa, and posed for many selfies.

The 19-year-old Jenner, the youngest child of Kris and Caitlyn Jenner, launched her own cosmetics line and is becoming a mogul in her own right, and E! has responded by giving her her own Kardashians spinoff series, Life of Kylie, which is airing this summer. The show promises to "expose a personal, more intimate side of makeup entrepreneur as she manages her celebrity persona, multi-million dollar company and, well, just being a teenager."

As the Sacramento Bee notes, Jenner has mentioned over the years that she wanted to attend a prom, having been home-schooled since ninth grade, and it sounds like Ochoa's plight, which was advertised through signs at the school and then via social media, caught the attention of a producer or one of Jenner's staff, who reached out to Ochoa’s family to offer this surprise.

Her 21-year-old sister Kendall made all the headlines last week with that now-pulled Pepsi ad, which has inspired a possible lawsuit by the SFPD, and a mocking sketch on SNL.
