Creator: Future uncertain for 'The Hills'

The Hills creator Adam DiVello has admitted that he cannot confirm whether the show will continue without departing star Lauren Conrad.

The 23-year-old has confirmed that she will be leaving the MTV scripted reality series at the end of its current fifth season.

Speaking to E! News, DiVello said: "I can’t even say if there is a next season. I have no information for you on The Hills beyond Lauren Conrad.

"We're focusing on this season, and this will likely be our highest-rated season yet. I think a lot of people are going to tune in to see Lauren wrap her storyline."

He described rumours that upcoming episodes would see Conrad patching up her relationship with fomer best friend Heidi Montag as "deceiving", adding: "It’s a rollercoaster ride for these two.

"They are at a point where they are ready to forgive each other. But there’s still this looming presence of Spencer Pratt in Heidi’s life, and that’s the thing Lauren is dealing with the most."
