Lauren Conrad will be nowhere to be found when The Hills returns Tuesday to MTV. Audrina Patridge has also said she is graduating from the reality soap. And now, it seems, the show will lose even more key players.

"I think Audrina, Lo and I are all going to leave after these 10 episodes," Stephanie Pratt tells "I don't know how much more I can take of The Hills ... The Hills is very brutal."

While Pratt faces off with newcomer Kristin Cavallari in an exclusive clip from tonight's new episode, she says that the Laguna Beach alum isn't the reason she wants to leave the show.

"It's not because of Kristin," she says. "I was going to stay and see what happens after these ten episodes, but I just don't think I can stand The Hills anymore."

In fact, Spencer Pratt's sister, who famously befriended her brother's enemy Lauren Conrad in fashion school, says The Hills will be a better show with the new addition.

"The show is going to be so awesome. It's not going to be boring like all the other shows where they only focus on their work," she says. "It's going to be new , new characters, which equals new story lines. It's going to be a completely different show."
