The BBC presenter then attempted to get the conversation back on topic as she asked Sadie about Tony.
Naga said: “So right Laila, Maddie, and Jemima. I heard them all in the background, hello. Let’s talk about grandad Tony.
Sadie divulged: “Well a lovely dad and just a wonderful grandad. He and my mum have looked after our girls while we have been working, all their lives.
“So they have just got such a great relationship with each other, you know.”
Naga appeared on Strictly five years ago alongside ballroom professional Pasha Kovalev, and the pair finished the contest in 12th place.
