Hugh Grant has (not so) secretly become a father for the third time.

The actor - who already has a 2-year-old daughter Tabitha, and a 13-month-old son Felix, with former lover Tinglan Hong - has also fathered another child with Swedish TV producer Anna Elisabet Eberstein. They became parents to a baby boy in September 2012, just three months before his youngest child was born.

By way of confirmation, 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 - but the 53-year-old actor is giving her his full "support".

The source told The Sun: "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." Of course she has their blessing; she got a swanky West London pad they can stay in when they visit. That and she's not calling them to babysit for her every two seconds.

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". Their relationship "fell apart after she became pregnant."

Despite that, he admitted becoming a father had changed his life: "Now that I have a child, it is life-changing. I recommend it. Get some."

Three, to be exact.
