“Will you and John get married?” asked Stern, 61, who takes credit for introducing them. “I would like to be at the wedding … Are we headed in that direction?”

“I’ll tell you what I’m leery of,” Brinkley quipped. “I am leery of discussing my relationship, because I don’t want to jinx it.”

The new pair sparked relationship speculation with a dinner date in September. Later that week, she was by his side for a taping of The Late Show with Stephen Colbert.

Brinkley told Stern she didn’t want to publicly discuss marrying Mellencamp because she felt “so dragged through the press” in previous years. Brinkley and first husband Billy Joel split in 1994. She married architect Peter Cook in 1996, but the relationship ended a decade later following his cheating scandal. As for Mellencamp, the “Jack & Diane” crooner was last linked to Meg Ryan, 53.

“Are you leery of this relationship because you’ve already been married to Billy?” Stern asked. “Are there parallels?”

“I love musicians,” Brinkley replied with a laugh. “I think artists are the most amazing people because they’re constantly creating beauty for the world. With all the crazy stuff going on in the world, then there’s artists reminding us of our humanity and reminding us of our heart and soul and what really matters. I respect artists so much and I absolutely love music as the ultimate art.”

While Brinkley is tight-lipped about a potential walk down the aisle, she made it clear she’s looking out for her new love after Stern mentioned Mellencamp’s smoking habit.

“This is one thing we have to discuss, and I’ve talked to John about this: he has to stop smoking,” said Stern. “He won’t do it. He thinks it makes his voice sound better.”
