In the midst of Michael's fame, scrutiny and surgeries, he married Lisa Marie Presley in 1994. Katherine, along with the rest of the world, was surprised by the nuptials.
"He called me after he had married her," Katherine says. "He said, 'I'm going to put her on the phone,' and he put her on the phone. I said, 'That's not [Lisa Marie].'"
"Had you met her before?" Oprah asks.
"No, I hadn't met her before," Katherine says.
Despite how quickly the relationship progressed, one thing Lisa Marie knew early on is how much Michael loved his mother, even telling Oprah that his love for Katherine was unconditional and there was nothing he wouldn't do for her.
"Did you feel that?" Oprah asks Katherine.
"Yes, I did," she says. "And everybody I talked to that knew him would tell me the same thing. I felt it too. I truly loved him."
