Jon Gosselin on Ex-Wife Kate: 'She Can Eat [Bleep] and Die'

Dave Kotinsky/Getty Images(LOS ANGELES) -- There's no love lost between Jon Gosselin and his ex-wife, Kate. They've been publicly feuding for months, but Jon raises the drama to a whole new level in Thursday's episode of the VH1 series Couples Therapy, on which he stars with his girlfriend, Liz Jannetta.

In a preview clip released by the cable network, Jon vents to Jannetta after speaking to his ex on the phone. Jon, who has eight children with Kate, suggests he'll fight for primary custody of the kids who want to live with him.

Then, in a profane rant, Jon declares, "It's narcissistic bulls*** behavior, 'cause she can go out and talk about the kids anytime she wants. She can tweet, have a f***ing website dedicated to them, every f***ing book she's ever put out because she wants to keep on being on television, which is never gonna f***ing happen, so she can eat s*** and die."

You can watch Jon sound off on Kate when Couples Therapy airs on VH1 at 8 p.m. Eastern time on Thursday.
