'90210': Behind the scenes with the Kardashians

The Kardashians will be dropping into "90210" for the season premiere and we've got a behind the scenes look at Kim and Khloe doing their thing in the Beverly Hills ZIP code.

"We're bringing clothes to AnnaLynne McCord's character, Naomi, from our store, Dash," explains Kim Kardashian. "And we're helping her pick something out. She wants to look extra-fabulous."

The problem is Naomi hasn't told the sisters that she's broke. So when they try to collect for the dress, the claws come out. 

"You know it's '90210,' so we got to make it catty," says AnnaLynne McCord. "There's aspects that are so real life and then there's everything else, which is so completely over the top. But, you know we are a show that's known to be an escapism."
