Presenter of Strictly spin off It Takes Two, Zoe Ball, said that she was "terrified" of her dad Johnny Ball's stint as a contestant.
Zoe was in the BBC One studio when Johnny made his first appearance on the stage.
The star said: "I was terrified. When I saw him on the balcony on Saturday's show, I needed to pace up and down! I had clammy hands."
Zoe, who has competed in the competition herself, isn't worried about her father being one of the show's more mature contestants, however.
She said: "He did really well. He has so much energy. I feel very proud of dad. Anything he does out there will be amazing and I am certainly not worrying about the fact he is the oldest contestant."
The former Radio One DJ has insisted she will not make it easy for her dad when he appears on It Takes Two.
She said: "It's going to be funny asking dad how his dance went, but I will be impartial. I definitely won't go easy on him. If anything, I'll be tougher on him."
