She's on the cover of this week's People, telling the magazine she's worried about maintaining the lifestyle she and her kids have become accustomed to thanks to the cash from the show.

    "I'm freaking out. Big time. ... I told them [my kids] I will work my fingers to the bone to make sure that they can stay here and go to their school. There are no guarantees in life for anyone, but they know that I'm giving it my best shot."

Well, maybe you should have been saving up, Kate!

Meanwhile Kate, 36, is getting blasted for her most recent on-air freak-out; she yelled at her kids and their nanny for handing the family's bodyguard, Steve, a piece of pizza bare-handed.

The nanny can be heard saying, "It's all about him [Steve], isn't it?" Gosselin and Steve have been rumored to be dating in the past.

Anderson Cooper tore Kate apart for the incident on his show -- watch the video below.
