Jon Gosselin Explodes Over Feud With Ex Kate: 'She's A Piece Of F**king Sh*t, A Sh*tty Human Being … She Can F**kin' Die'

Jon Gosselin's bitter feud with ex-wife Kate Gosselin reached a new boiling point in a preview clip of Couples Therapy obtained by RadarOnline.com, when the father of eight slams Kate in an expletive-filled rant, calling her a "piece of f**king sh*t," a "sh*tty human being" and says, "She can f**kin' die."

Frustrated by his damaged relationship with Kate and the multi-million dollar lawsuit she filed against him, Jon finally explodes after a text conversation with her.

"Great f**kin' wife. Why do I f**kin' try?" he asked his girlfriend, Liz Jannetta.

"It's narcissistic, bullsh*t behavior. And she can go out and talk about the kids anytime she wants! She can tweet and have a f**kin' website dedicated to them, every f**kin' book she's ever put out because she wants to keep being on television which is never gonna f**kin' happen, so she can f**kin' die."

And just when you think he's cooled off, there's more: "There's your honest depiction of Kate Gosselin. Piece of f**king sh*t. What a sh*tty human being."

Earlier in the clip Jon is less agitated, telling his Couples Therapy cohorts about his tell-all book and reveals his favorite phrase about Kate.

"I wrote my book, I'm just afraid to publish it. It took my two years. It's everything that happened…my side, my emotions. And then the legal team gets involved and says, 'You can't say this, you can't say that, that's defamatory' but if I say 'I feel,' they can't take away your feelings, because no one can tell you how you feel. It's not defamatory or libelous," he explains.

"The lawsuit, that hurts me. It's like, I would never do that to her. I don't care how bad sh*t was. She's suing me for millions. I live in a three-bedroom cabin!

"That was my statement: You hate me more than you love your children."
