Head Strictly Come Dancing judge Shirley Ballas has revealed she’s a grandma, or as she likes to call herself, Glamma Shirley. Shirley's son, Mark, 37 and his wife BC Jean, 36, are feeling blessed after the birth of their son Banksi Wylde Ballas, especially after suffering a miscarriage last year. While Shirley hopes to be a hands-on grandparent, that will prove tricky with Mark and BC being based in Los Angeles.
