Entertainment Tonight.Jon Gosselin loses his cool, quiet demeanor when talking about claims that he and his wife are exploiting their children to film them on "Jon & Kate Plus 8."

In a new interview with People magazine, the embattled father speaks out for the first time on his family woes. Jon appears on the cover with the headline "Enough is enough!"

When the conversation turns to allegations that his children are being exploited on their reality show, he blasts back at critics. "Exploited?" he asks. "I don't even want to use that word, because I think it's ridiculous." He is adamant that his children's happiness has been and will continue to be his main priority, even if that means quitting the show.

The new issue of People is on stands Friday.
