Mariah Carey and Nick Cannon to debut twins in TV special

Mariah Carey and Nick Cannon's baby twins will make their TV debuts as part of a special later this week (begs17Oct11).

The Hero hitmaker gave birth to daughter Monroe and son Moroccan on 30 April (11) - the same day the couple celebrated its third wedding anniversary - but the tots have been kept hidden from the spotlight, until now.

The babies will take their TV bows during an interview with newswoman Barbara Walters, who was invited to chat to Carey and Cannon and meet the kids in their New York home.

A post on Carey's website reads: "Mariah and Nick recently sat down with Barbara Walters in their New York apartment to discuss Mariah's pregnancy, their marriage, their beautiful baby twins Monroe and Moroccan and much more."

The interview will air on news programme 20/20 on Friday (21Oct11).
