Stephanie Pratt promises “The Hills” reboot will deliver the sort of drama that can tear families apart and ruin lives.

“The Hills: New Beginnings” is on the way and Pratt is genuinely worried about the impact the show will have on the cast.

“It was really fun at first, and now it’s like a nightmare,” Pratt, 32, told Us Weekly at a Beverly Hills jewelry event she hosted. “You know, the stakes are a lot higher.”

“We’ve got couples who are married with kids. It’s not kind of just like, ‘Oh, you cheated at the bar.’ This is way more life-changing kind of stuff,” Pratt explained. “I’m scared for everyone. And for myself. It’s going to be gnarly.”
