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

The 42-year-old actor's ex, Catherine Harding (you may recall her from a stint on You're a Star...), is around eight months pregnant with his fifth child, who the internet reckons is a girl for some reason - what with this tweet doing the rounds from Harding's baby shower featuring 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." A giveaway if ever there was one. 

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 23-year-old also took to Twitter to post a picture of herself getting down with some pals at the soiree.

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 (whom he just bumped into after one of his Broadway shows in 2009), which kind of makes him the male equivalent of Katie Price - 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."

According to The Mailonline, Jude is currently renting a house in North London's Hampstead Heath for Catherine ahead of her impending birth in February.
