Mariah Carey's twins make their television debut tonight as the music superstar and her husband Nick Cannon sit down with Barbara Walters for an interview in which Mariah discusses her marriage and reveals new details about her pregnancy.
In an exclusive interview airing tonight on ABC's 20/20, Mariah admits that she experienced a miscarriage before she became pregnant with twins Moroccan and Monroe. She also tells Barbara that she used acupuncture for relaxation and underwent fertility treatments to get pregnant. "The main thing I did that was tough -- was to go on progesterone like every month… and then when I was pregnant, I had to stay with the progesterone for 10 weeks. It minimizes the chance of miscarriage by 50 percent."
Nick said the pregnancy was a happy event, but he also had concerns. "It was good news but it was scary news at the same time." Mariah added: "I don't think I understood the enormity and the magnitude of what it really does to your body. Like it's not just, 'Oh, you don't look pretty and you have a bump -- no.' Unless somebody's been through it, it's difficult to understand what I went through because my pregnancy was very unique in terms of what happened to me."
Mariah said although the failure of her first marriage to record executive Tommy Mottola made her "afraid of the concept of marriage," this time has been a happy experience. "But this is a different situation and… I'm a different person. It's a different time in my life. And nobody will ever be able to steal my spirit again. So I'm just happy to be in love and to be here." On her husband Nick, she jokes: "When he's nice, he's the best guy in the world."
Barbara spent time with the couple and their new babies and Mariah even demonstrates how she sings to the twins. She also revealed that during the pregnancy she used a special belly attachment for her iPod that allowed her to play music -- including her own songs -- that her babies could hear in the womb.
Nick said while he's confident the twins inherited the musical talent from their mother, he also wants them to excel in their educational pursuits. "I want them to be able to sing as beautifully as their mother. I want them to be able to play instruments and everything. But I want them like … ‘Go get a Ph.D.'" For her part, Mariah said the twins are "incredible" and will be able to do many things, but she emphasized: "They really respond to music."
