Trouble In The Hills

The Hills aren't alive with the sound of girly chatter. Lauren Conrad and Heidi Montag are apparently so over one another that MTV is having mucho difficulties in promoting the show's new season. "Lauren and Heidi refused to even be in the same room as each other," an insider tells Page Six. "They hate each other so much. In the photos on MTV's site for the third season, they had to Photoshop Heidi in because they wouldn't even take a picture together." (MTV's response? No comment.)

Could this spell trouble for a possible season four? Stay tuned…

You Say!
