Mariah Carey, Nick Cannon Debut Twin Babies

Mariah Carey and Nick Cannon recently sat down with Barbara Walters for their first interview since the birth of their twins, giving viewers an intimate glimpse of their family life, and introducing their 6-month-old twins Monroe and Moroccan (aka Roc and Roe) to the world.

The 'Always Be My Baby' singer and her television personality husband, who have been hitched since 2008, invited Walters into their New York home to discuss marriage, parenthood, Carey's high-risk pregnancy and Mariah's trust issues on the special episode of ABC's '20/20.'

A preview of the exclusive interview, which airs Friday (Oct. 21), has hit the 'net, revealing Mariah's trimmed-down post-baby body, as the new mother coos her hit 'We Belong Together' to her little babies.

The interview airs Friday (Oct. 21), at 10PM ET on ABC's '20/20.'
