Hugh Grant has fathered a third child, a little boy with Swedish TV producer Anna Elisabet Eberstein who was born just three months before his youngest son Felix.
Grant - who has daughter Tabitha, two, and son Felix, 13 months, with former lover Tinglan Hong - and Swedish TV producer Anna Elisabet Eberstein became parents to a baby boy in September 2012, just three months before his youngest child was born.
A source said: "They were pregnant with Hugh's children at the same time. It's an unusual arrangement."
Hugh's name was initially left off on the little boy's birth certificate but in December the document was updated to include the identity of his famous father.
It is not known whether Tinglan is aware of Hugh's relationship with Anna - who lives in west London with the little boy, whose name has not been revealed - but the 53-year-old actor is giving her his full "support".
The source told The Sun newspaper: "Anna is being supported by Hugh all the way. She lives in a very comfortable property in West London and knows that Hugh is there for her.
"Anna's parents in Sweden know all about the relationship and she has their blessing."
The 'Love Actually' star revealed he had fathered Tabitha two months after she was born and described his relationship with her mother as a "fleeting affair".
He also admitted becoming a father had changed his life.
He said: "Now that I have a child, it is life-changing. I recommend it. Get some."
