HLN professional spitfire Nancy Grace took on TLC’s Jon Gosselin to task on Monday night’s episode of The Insider.

Gosselin — who recently came underfire for allegedly stealing a portion of his family’s multimillion dollar Jon & Kate Plus 8 fortune — squirmed helplessly during the verbal smackdown.

“You talk the talk but you don’t walk the walk. You can’t go out with one 22-year-old after the next while she’s at home with the children and say you want to work it out.”

This dude seriously needs to grow a sack. Watch and weigh-in.

Did Nancy go too far?
