Jude - who has three children, sons Rafferty, 18, and Rudy, 12, and daughter Iris, 13, with his ex-wife Sadie Frost, is step-father to her 24-year-old son Finlay, and also has a five-year-old daughter, Sophia, with model Samantha Burke - recently admitted he is "happy" to be expecting a fifth child.
He said: "There's always sensing the presence of age. I've done 57 films. Looking back, I can't believe I'm still working and maintaining my position.
"But I'm a happy man these days. Four children, another on the way.
"My 18 year old's in the business. My 24 year old, a gifted musician on piano and guitar, studies music in college. They're my bedrock."
The 'Dom Hemingway' star - who was married to Sadie from 1997 to 2003 - announced in October last year that he was to be a father for the fifth time but confirmed he had split from Catherine.
A spokesman for the actor said: "I can confirm that Jude Law and Catherine Harding are expecting a child together in the spring.
"Whilst they are no longer in a relationship, they are both wholeheartedly committed to raising their child.
"They consider this a private matter and other than this confirmation no statement will be made.
"I ask that you respect the privacy of all parties involved and their families."
