Lauren Conrad & Heidi Montag

The Hills is arguably one of the most dramatic reality shows in history. It showed the infamous feud between Lauren Conrad and Heidi Montag, which started when the former suspected that the latter and her boyfriend, Spencer Pratt, were behind a private tape.

In the reboot of the show, which is currently filming, Conrad is noticeably missing from the lineup, which is probably because of their problem. Montag previously revealed that her former friend was unwilling to make amends because she holds grudges. The Hills: New Beginnings is enough proof the two wouldn’t work together anymore.
