Jude Law is to become a dad for the fourth time following the revelation from his ex that she is seven months pregnant with his child.
The single Sherlock Holmes actor, who already has three children with ex-wife Sadie Frost, allegedly had a love affair with the unnamed woman in December last year.
A source told The Mirror: "His relationship with the girl was a passing fling, nothing serious. It was supposed to be a bit of fun for the both of them. He had no idea she was pregnant until she called and told him."
They added: "Jude is a family man and he would not choose for a child to be born under these circumstances. But he wants to behave honourably."
His publicist released a statement saying: "Jude Law can confirm that, following a relationship last year, he has been advised that he is to be the father of a child due in the fall of this year.
"Mr Law is no longer in a relationship with the individual concerned but he intends to be a fully supportive part of the child's life."
Law apparently broke the news to Frost and his children on Tuesday.
