Stephanie Pratt on 'Hills' Finale: "It Was All Pretty Real"

While her co-star Kristin Cavallari claims The Hills is all fake, reality star Stephanie Pratt wants to clear the air about tonight's big season finale. Yes, fans have even come to realize that the hit MTV show is somewhat scripted, but tonight's finale promises to be "pretty real" according to Stephanie.

“Nothing was really set up in advance. It was all pretty real,” Stephanie told Fancast.com about the finale.

Stephanie maintains that most of what is seen in the show, represents what is going on in the stars lives.
