Son Moroccan Scott and daughter Monroe – their folks call them Roc and Roe – are introduced to Barbara Walters, who interviews the parents inside their Manhattan apartment. The segment airs on Friday’s 20/20 at 10 p.m. ET.
In a teaser clip, Walters asks Carey if she trusts Cannon. “Sometimes,” replies the songbird, as Walters raises her eyebrows.
