A possible answer to a great question...

The last Divine Adoratrice was the princess Ankhnesneferibre, daughter of Psamtik II, adopted by Nitokris I, who became the God’s Wife of Amun (aka - Divine Adoratrice) in year 4 of the reign of her brother Wahibre. Nitokris II - daughter of Ahmose II and Ankhenesneferibre’s intended successor for the title, most likely never took up office due to the Persian invasion of Egypt lead by Cambyses in 525 BCE.
