As part of an episode to mark St David’s Day, Sheen spoke of how Lyra had got used to people approaching her dad.
“It started with people coming up, saying hello and wanting to talk to [me],” Sheen said.
“And I could see her starting to notice this when she was very little.
“The first thing she started doing was, if somebody came up to me, she’d say, ‘and my name is Lyra’.”
“Then if it was a photo, ‘can I be in the photograph?’
He said that the interactions had now evolved to “this thing like she’s my agent”.
“She’ll suddenly shout out ‘Michael Sheen is in the building!'”.
He also revealed he had been dubbed “Sheenie the genie” by his youngest daughter Mabli after his role in Swansea Grand Theatre’s Christmas pantomime, Aladdin.
