The season 1 cast took a walk down memory lane, sharing their favorite memories, and even playing "Never Have I Ever" and a game of trivia during the 30-minute reunion.
"I feel like the last time we all might have been in the same room was when we were going to the VMAs one time," Colletti recalled. "MTV was like 'Here, we're going to launch this show and here's 45 minutes of media training. Go have fun and then this show is going to air on MTV. Good luck!'"
The cast also dished on the "inauthentic" scenes of the show and how they had to redo many of them.
"We did a lot of pickup scenes where it was definitely out of order," shared Cavallari. "And we had to pretend like prom just happened. [Then we'd be told], wait, pretend like prom hasn't happened."
They did admit that they have never rewatched the show as adults, but couldn't have been more grateful to be a part of TV history.
"I've seen minutes of it, but I've never re-watched the whole thing," said Cavallari, with Phillips adding, "It's crazy because I remember watching it when it first came out and every time you're like, 'That's not exactly how it was. They changed this.' Then all of a sudden, 10 years later, you're watching it and you're like, 'Oh that b**ch.'"
Among the highlights also included Coletti sharing how he always has people "shout my name in the way that Kristin liked to pronounce it."
"They try to say it and it's really, really funny because they look pretty ridiculous," he quipped, with Cavallari adding, "People are always asking me to say it. I'm like, 'Come on man!'"
When answering fan questions, they shared if they would do reality TV again, how the kids at their school felt about them filming the show, their favorite episodes to film, their parents' thoughts and more.
