The Hills are still alive - at least for female fans.
The MTV reality show's fifth season premiere Monday had the highest TV ratings among females aged 12-24 and 18-24.
The back-to-back episodes averaged 3 million viewers, down about 15 percent from the season four premiere. In comparison, season three attracted 4.8 million viewers.
Producers say they still haven't decided whether to continue the show without Lauren Conrad, who is leaving after this season.
Heidi Montag recently told MTV News the show could still thrive without her former BFF.
"We'll miss her. I just don't know if we need her," she said. "She's gotta leave the dramas to the pros! I love The Hills and I definitely don't want to go anywhere anytime soon. That's my home and I'm so grateful to be on it, so we'll see."
