Jude Law is expecting a girl with his ex-partner.

The 42-year-old actor's ex Catherine Harding is around eight months pregnant with his fifth child, who appears to be a daughter as one image of his former flame's baby shower featured a pink and yellow cake complete with a pair of pink booties on the top and a star decorated with the message: ''It's a girl.''

Catherine - who is also known by her stage name Cat Cavelli - can be seen cradling her baby bump in a group shot from her ''belly party'' posted online by one of her friends who attended the bash.

The raven-haired beauty, 23, also took to Twitter to post a picture of herself with some of her pals at the baby bash.

She captioned the image: ''Love these girlies and the rest :) thankyou for such a lovely weekend xx (sic)''

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.''
