For shows that depict reality, you can expect a lot of manufactured changes on The Hills and The City come their September 29th premiere.

Liz Gately, senior vice president of MTV series development and executive producer of both shows, fills us in on a few scripted realistic developments.

Most noticeably, Kristen Cavallari has replaced L.C. on The Hills.

“Kristin has brought new life to the show,” Gateley said. “She is the same Kristin we know and love — not afraid to mix things up. Her presence has really changed every dynamic within the cast, especially with Audrina [Patridge] and Justin Bobby.”

And now that Speidi are married, they are taking a big step in their relationship!

“Heidi and Spencer are entering some interesting new territory of considering parenthood,” she continued.

The big city life of Whitney Port in NYC has been altered as well!

“A lot has changed in The City,” continued the reality plot maven. “We shifted the focus of the show significantly from a relationship drama to a workplace drama. Olivia has a new job and an amazing new boss at Elle magazine. Whitney is focused a lot more on her work now that she’s single, and Kelly Cutrone — who I love — takes on a much bigger role in the show.”

Gately also mentions that the shooting style changed. There will be less scenes with people sitting and talking and more action. The new season can be compared to “a reality Devil Wears Prada.”

The only difference is that Meryl Streep would rather kill herself than be part of it!
