Sir David Jason met his actress daughter that he was unaware existed multiple times without knowing they were related.
It comes after the Mirror revealed that Sir David discovered that he had a 52-year-old daughter with Jennifer Hill.
Since he met Abi Harris the pair have met up on several occasions, spending some of the festive period together.
However, the father and daughter have crossed paths several times through mutual friends... but he had no idea they were related.
Jennifer was married to screen star Geoffrey Davion, who appeared in Miss Marple and The Stars Look Down, and Abi believed he was her father until his death in 1996.
Jennifer, who has appeared in Doctor Who and James Bond film, Octopussy, and Sir David were reunited in 2008 for a reprisal of Under Milk Wood, with Abi also starring alongside them.
However, it was another five years until Abi started to suspect Sir David could be her real father.
Abi and Sir David were standing next to one another at an event when she spotted they had similar side profiles.
It was watching her son, and David's grandson, 10-year-old Charlie grow up that urged her to act.
Abi bravely decided to write Sir David a letter asking him to do a paternity test.
When the test came back positive, the family met up at the Landmark Hotel in Marylebone, Central London, to discuss how to connect.
Abi said: "In discovering my father’s identity, I am starting to piece together my own.
"Of course, I am tickled pink and incredibly proud but, frequently, completely overwhelmed with sorrow for the years we have lost.
"After a measured start, now I hope we can consciously make time to see each other more often, so that I can master the art of being the best big sister and build a meaningful father-daughter relationship in its truest sense."
Sir David said: "To say it was a surprise to find out I had a daughter from years ago is an understatement.
"However, on settling with the news, I am delighted that I am now able to get to know Abi and so we meet up when we can.
"My wife, Gill, and daughter, Sophie, have been very supportive and understanding and have embraced Abi and welcomed her and her young son into her now wider family."
