Jon, who has been in a relationship with Colleen Conrad for six years, also touched on his up and down battle with his ex-wife.
He said: “It’s not an easy battle. I had shared custody. I lost some kids. I had joint legal, I lost legal.
"I got legal back. By the time... when Hannah was 12 years old, she wanted to live with me, so then I had to go get legal again.

He continued: “I’ve been through nine attorneys. I’ve probably spent $1.3 million in court, back and forth with everything else.
“And then I got sole custody of Collin. Kate has no contact with him. So, there was a whole bunch of stuff that happened with him.”
