The same cannot be said of Heidi Montag, America's most notorious frenemy.
During a therapy session on Marriage Boot Camp: Reality Stars, Montag finally forgave Conrad for the dissolution of their friendship.
"I forgive you for being so insecure in your life and so frustrated for everything that you went through that you felt like you had to blame it on me because I was easier," Montag told a Conrad stand-in during the bizarre exercise which, remarkably, everyone managed to take seriously. "I forgive you for trying to ruin my life."
It has never been 100 percent clear what caused the rift between Conrad and Montag, but during Season 3 of The Hills, it was implied that Montag and her then-boyfriend (now husband) Spencer Pratt were the ones who'd started the rumor that Conrad and her boyfriend at the time, Jason Wahler, made a sex tape. Conrad and Montag then got into a screaming match outside an L.A. nightclub (a sentence that proves why The Hills is one the greatest shows in television history). From that point on, Lauren and Heidi were total enemies.
Apparently Heidi has been seething about it ever since.
