NEW YORK (AP) — The newest reality television show is in some ways like any other: mother and daughters, sibling rivalry, family gossip and talk of Big Grandpa, who is very strict but loves it when his great-grandchildren are around making a racket. But that's where the twist comes in: Big Grandpa is Nelson Mandela, the anti-apartheid legend.

"Being Mandela," a new series premiering Sunday on COZI TV, invites U.S. audiences into the lives of Zaziwe Dlamini-Manaway and Swati Dlamini, the fashionable, 30-something granddaughters of Mandela and Winnie Madikizela-Mandela. The 94-year-old former South African president, who recently was treated for a lung infection and had surgery to remove gallstones, does not appear in the series but his controversial ex-wife — "Big Mommy" to her grandchildren — does and seems to relish it.

If the Mandela clan seems like an odd subject for a reality show, the granddaughters make no apologies.
