The former Sunrise host revealed on Tuesday that her “beautiful” grandmother, Dorothy Flannery, had died at the age of 100.

“She was 100 and she was just pure magic.”

In her emotional tribute, Armytage shared personal messages from friends of the family, reflecting how widely her grandmother was loved.

“A grandmother’s love is like no other.”

Another simply wrote: “She deserves a good rest but Lordy, we shall miss her.”
