Ms. Shields was asked about her experience with Mr. Trump.

“I was making some movie in the late-90s,” she said. “My phone rang and it was him. He said, ‘You and I should date. You’re America’s sweetheart, and I’m the world’s richest man. People will love it.’ At which point I stifled laughter and said, ‘Thank you, I’m very flattered, but I have a boyfriend and I don’t think he would appreciate me stepping out on him.’ And he said, ‘Well, I think you’re making a big mistake.’ I said, ‘Well, I’m going to have to take my chances.’”

Did she not know that George Michael was gay? And did they really go on a date?

“A few,” she said. “He was very respectful of my virginity.”

“Read the book!” a publicist yelled, referring to “There Was a Little Girl,” the 2014 memoir in which she tells the tale.

Ms. Shields added that, despite the appearance that her relationships with Mr. Michael and Mr. Jackson seemed merely for show, she had real bonds with both of them.

“We had so much fun,” she said. “I wasn’t just a purpose, as a beard. It actually was more than that. The conversations, the fears, the discussions.”

The talk turned to her podcast — in which she has spoken with Stacey Abrams, Rosie O’Donnell, Chelsea Handler and Kris Jenner — and the one person she has been itching to get: Britney Spears, who hasn’t given an interview in years.

“I tried very hard to find a way to be the first actual interview,” Ms. Shields said. “And I haven’t gotten it. But I am the only person who could do justice to the reality of the story. Whatever it is.”
