Looks like Lauren Conrad may have even more BFF drama in the upcoming fourth season of The Hills, which premieres August 18.
Frenemy du jour: Stephanie Pratt.
In a new trailer, Lauren Conrad confronts Stephanie about going on a date with her handsome new baseball player beau, Doug Reinhardt.
Meanwhile, Lo Bosworth and Audrina Patridge confront their own drama, and Heidi Montag and Spencer Pratt are — wait for it — fighting.
This time, a stubborn Spencer Pratt says he's moving out of their apartment if Heidi's sister, Holly Montag, becomes their third roommate.
Here's a clip of some of the action to come. Follow this link to MTV for the official, expanded trailer of Season 4 (which we'll post ASAP).
