And... on to the next one, or should that be former one?
He was set to marry actress Julia Bernheim when Pamela apparently texted him to ask him to marry her.
"Needless to say that when [Pam] texted me that she wanted to get married, it was kind of a dream come true, even though I was engaged to someone else and the lady was moving in," the 74-year-old told Page Six.
But now Jon has reignited his romance with Julia, who bears striking similarities to a young Pamela.
According to The Sun, Julia, known professionally as Julia Faye West, has had small acting parts in TV series. She’s also acted in a few films, including Mob Rules (2010), After School Massacre (2014) and Ballet of Blood (2015).
The news of their rekindled relationship comes after Pamela fired back at claims by Jon that she used him for money to pay off her $200 000 (R3 million) debt.
The Batman producer has since denied the statements and insists he never made the claims.
"I haven’t spoken to the press – nobody. I’ve loved this kid since she was 20 years old. I still love her. We’re friends. We’ll always be friends," he explained.
"I helped her in a way that she needed, but it’s between her and I. I think she’s great, and that’s all I got to say."
