The son of Janet Brown and Peter Butterworth, Tyler Butterworth, was born in 1958.
That makes him 48. It is highly doubtful that his mother was married and had him by the age of 14 or 16. (They were married at the time of his birth). He is married to Janet Dibley, by the way.
All the websites I've looked at give her date of birth as 1926. She was presenting a children's' programme, Picture Book, in the 1940/50s. Janet's acting credits go back to 1949, and she was not a child actor.
I cannot believe she is in her 60s.
But isn't it Faith Brown who is to be in I'm a Celebrity? She was born in 1944, so is 62.
