bus for the class of ’9

Unlike sisters Kourtney Kardashian and Kylie Jenner, Kim Kardashian is not at Coachella this weekend. (At least, not yet.) And she's not in Cleveland, either, despite the fact that sister Khloé just gave birth and is in the midst of a rather dramatic scandal. Rather, Kim Kardashian is in California for a far more pressing engagement: Her 20-year high-school reunion, an event she broadcast in detail on Snapchat and Instagram Friday.

The saga opened inside a party bus, where mylar balloons spelled out “Class of 98” and “MHS” over a leather banquette. “Of course, I had to get a party bus for the class of ’98,” Kardashian explained, “and all my yearbooks waiting.” She cut to a spread of several yearbooks from her high-school years—Kardashian, now 37, graduated from the all-girls Catholic school Marymount High School in 1998.

“Hey guys,” she addressed her audience, “so, I am on my way, in a party bus, to my 20-year Marymount High School reunion, with my friends who I haven’t seen in 20 years.” Those friends, she reported, were concerned they might see fellow students at the reunion “that they were mean to,” but Kardashian had no such qualms: “I feel so good about my conscience,” she said in the Snapchat video. “I was so nice to everyone.” (Her friends, in the background, laughed.)
