Fighting between Hills cast members became an integral part of the iconic series — and Lauren Conrad more often than not found herself in the middle of all the showdowns. Let these five words serve as a reminder: You know what you did.

In honor of the show’s recent 10th anniversary, MTV followed the Laguna Beach native in an upcoming special, The Hills: That Was Then, This is Now — and in an exclusive sneak peek from the installment (airing on Tuesday!), the fashion maven opens up about those small-screen spats.

“I don’t want to say it was forced, but it was definitely encouraged. Because, typically, if you have a fight with your friends, you don’t pick up your phone for a few weeks,” Lauren explains in the clip above. “But when you have a scene scheduled with them two days later, you kind of have to talk about it.”

And you better believe she spoke about lots of issues with her cohorts back in the day. But which disagreements stand out? Watch the video to find out, stay with MTV News for more updates regarding this pop culture milestone and be sure to catch The Hills: That Was Then, This is Now on Tuesday, August 2 at 9/8c (another glimpse from the installment is featured below)!
