Say hello to Morrocan and Monroe.

Mariah Carey and her hubby Nick Cannon debuted their 6-month-old twins nicknamed “Roc” and “Roe” on ABC’s 20/20 Friday night.

The twins were dressed in their Sunday best for the big reveal, as Barbara Walters interview the family in the nursery of their New York City apartment.

During the interview Mariah (who appeared svelte and up-beat), talked about the difficulties she encountered while being pregnant, and the couple also revealed having a miscarriage.

“I don’t think I understood the enormity and the magnitude of what it really does to your body,” Carey said. “Carrying two babies. 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.”

During her pregnancy the self-proclaimed diva suffered from gestational diabetes, was at a high risk for seizures and ultimately put on bed rest for an extended period of time.

Morrocan and Monroe were born at 35 weeks on Mariah and Nick’s third wedding anniversary, April 30. During labor Mariah had Nick play a live version of her hit song “Fantasy.” “I wanted them to hear the applause,” Carey said.

The couple affectionately calls their twins “Dem Babies” and has launched, a site devoted to cute images of their children.
