She went back to school! Kim Kardashian celebrated her 20-year high school reunion over the weekend with a trip to her old stomping grounds: Marymount High School. The Keeping Up With the Kardashians reality star and makeup maven showed up to her high school in style.

Kim wore a plunging white dress and see-through heels to the event, said in one of the vids, "Of course I had to get a party bus for the class of '98." The bus was decked out with balloons and a stack of yearbooks.

"I'm so nervous!" she told her friend Allison in one Snap. "Should I wear my name tag?" LOL — we think it's safe to say you don't need your name tag, Kimmy. She then proceeded to take tons of Snapchats of her reunion, posing on the high school desks, videoing herself walking through the halls, and more.

The 37-year-old — who is mom to daughter North West, son Saint West, and daughter Chicago West, who was carried via surrogate — graduated in 1998 from the Catholic, all-girls private school in Bel-Air.

However, she didn't end up graduating from college — only sissy Kourtney Kardashian put in her time at university. Kim did a stint at Pierce College but soon after enrolling, KUWTK started up and she quit in favor of becoming a reality TV star.

As far as whether she was nervous to see people from her past, Kanye West's wife didn't seem too worried. "So my friends are worried that we're gonna run into people that they were mean to and I feel so good about my conscience, that I was so nice to everyone," she said.

As she later walked the halls with her classmates, she said, "This is so crazy, these halls. You guys, do remember these halls? So insane!" We can't wait to see what Kim ends up wearing to her 30 year reunion!
