David Jason discovers he has another daughter - we look at other celebrity long-lost children

In a scene that would have fit in well in one of David Jason's many drama roles, the moment he discovered he may have a second daughter came through the post in the form of a letter.

The actor, who was knighted in 2005 for his services to acting and comedy, spoke to the Mirror to reveal he has been getting to know his long-lost daughter, Abi Harris. She had sent him a letter, beginning with a Dylan Thomas quote that was from the play that her mother - Jennifer Hill - and father (David) had worked together on in 1970.

Sir David has been married to Gill Hinchcliffe since 2005 and they have a 22-year old daughter, Sophie Mae. The family have welcomed Abi and her son - David's grandson - with open arms as they adjust to making up for lost time with these new relations.

We take a look at some other long-lost celebrity families.

Liv Tyler

The actress Liv Tyler only discovered her father was actually Steven Tyler, the frontman for Aerosmith, when she was 11 years old. For the first decade of her life she believed Todd Rundgren was her dad. It was the during the 1970s that the mother of Liv - Bebe Buell - had dated Tyler.

Despite Rundgren being aware of the chance that Liv was not his daughter, he signed the birth certificate anyway and was, to all intents and purposes, the father of Liv. He gave her his last name and provided financial support.

Liv had her doubts on who her father was and even suspected that Tyler was in fact her biological dad. She even wrote in a diary as a child, 'I think Steven is my father'. Liv had posters of Aerosmith on her bedroom walls and had met Tyler after one of his concerts alongside her mum.

She described the encounter of meeting Tyler to the Guardian: "It was almost spiritual. When you meet kin, there is an energy and sparkle between your bodies. It must be chemical somehow – DNA and genes. I felt a connection in a very strong way when I met him as a little girl and I didn’t know why at first, but I figured it out rather quickly."

Her mum later admitted to Liv that Tyler was in fact her biological father. She has managed to stay close to Rundgren, as well as building a good relationship with Tyler.

Paula Yates

Journalist and presenter, Paula Yates, did not know who her real father was until she was under the celebrity spotlight in 1997. It took a DNA test to reveal that Hughie Green, the Opportunity Knocks host, was actually her biological dad.

She had believed Jess Yates, a presenter, was her biological father. When the News of the World newspaper printed the claims of how Hughie Green could be her dad, it could not have come at a worse time for Paula, as it was days after the funeral of Michael Hutchence - her partner and father of one of her children.

Her mum had denied the claims and therefore Paula took a DNA test to disprove what was being alleged. However, the test confirmed that Green was her biological father.

Arnold Schwarzenegger

The Terminator star managed to keep his secret child with the family's maid, Mildred Baena, hidden for more than a decade before he finally admitted what had happened to his wife, Maria Shriver, during a couples therapy session.

Arnold only discovered the son, Joseph Baena, was his when the child was eight years old. It led to Maria moving out of the family home and she filed for divorce.

He now has a good relationship with his son.

Daisy Lowe

The fashion model believed her father was the fertility specialist Bronner Handwerger, her mum's former partner. She only realised something was amiss when neither of her parents shared her O-type blood and asked for a paternity test.

The test revealed that her godfather, Gavin Rossdale - the lead singer of Bush - was actually her biological dad. This resulted in Gavin cutting off all contact with Daisy and her mum, Pearl, but they've since healed their rift and now get on much better.

Eddie Murphy

Eddie dated Mel B, Spice Girls singer, in 2006 after his divorce. Mel became pregnant near the start of the relationship and Eddie was not convinced he should take responsibility until a paternity test had been taken.

After a court case battle, the DNA test confirmed that the daughter, Angel Iris, was the child of Eddie. He was ordered to pay £35,000 a month until she reaches the age of 18.

Steve Jobs

The Apple co-founder, Steve Jobs, split up with his high school sweetheart, Chrisann Brennan, when she told him she was pregnant and he denied any responsibility.

When Lisa was born, Steve continued to publicly deny he was the father - even after a paternity test proved otherwise.

It was years after leaving Apple that Steve attempted to reconcile with his daughter and apologised for his behaviour. It was a strained relationship even afterthis and he left Lisa a multi-million dollar inheritance upon his death from cancer in 2011.
