KATE GOSSELIN’ kids more than miserable because of WIFE SWAP gag order.

For a new how peeming on ABC octo-mum Kate swapped “lives” with ex- playmate Kendra Wilkinson and NOW insiders report the trauma yet another “reality” show has wreaked on her children.

The two former Dancing with the Stars contestants filmed last year for ABC’s new spin-off, Celebrity Wife Swap, and author Robert Hoffman said “the Gosselin children were scared and very confused, having no idea who their new mom-for-a-week was, or why they were left alone with her to be filmed by strangers.”

Kate, the 37-year-old former TLC star and 27-year-old Playboy Playmate will indeed switch roles in front of the camera for a week, with Kate overseeing NFL hubby Hank Bassett and son Hank Jr., while Kendra will watch over Kate’s brood of eight, RadarOnline.com reported.

Hoffman added that the eight children had to suffer in silence, as they “were instructed not to speak a word about it to anyone at school or anywhere else.

 “I’m not sure how much more psychological damage Kate can do to these poor children, but she sure looks like she’s willing to sink to new depths to get her face back on television,” Hoffman wrote .
