It looks like Jude Law should dust off his diaper-changing skills next spring. The British actor is expecting a child with ex-girlfriend Catherine Harding. It will be his fifth child but his first with her.

"I can confirm that Jude Law and Catherine Harding are expecting a child together in the spring,” the actor’s rep revealed in a statement. “They consider this a private matter, and other than this confirmation no statements will be made. I ask that you respect the privacy of all parties involved and their families."

Although Law and Harding are “no longer in a relationship,” the actor’s rep explained that the two will be “wholeheartedly committing to raising their child.”

The 41-year-old Hollywood star has three children with his ex-wife Sadie Frost: son Rafferty, 18, daughter Iris, 13, and son Rudy, 12. Law also had a daughter Sophia, 5, with model Samantha Burke.

Who is Law’s newest baby mama? According to reports, Harding is a 23-year-old Irishwoman who is an aspiring singer-songwriter. She goes by the stage name of Cat Cavelli, currently lives in London and made her big claim to fame when she was introduced to the U.S. by American gossip blogger Perez Hilton.

The gossip king posted Harding's music video, titled “Cruel Melody,” to his website. “Take Demi Lovato, add some British coolness, some Madonna Frozen, some Laura Mvula and a whole lot of awesomeness and you have Cat Cavelli,” he gushed. Fans can check out Harding's music on her YouTube channel or through her SoundCloud account.

Harding and Law reportedly began their brief relationship in the summer. The two were spotted getting cozy with one another while Law was shooting on location in the Czech Republic. “It all happened very quickly,” a source revealed to MTV. “They met a little while ago and fell for one another, then Cat told friends that she was going out to Prague, that's when it emerged that she was in a relationship with Jude."

Their steamy summer romance was short-lived, but she is now five months pregnant. “Sadly they are no longer a couple but they are both so determined that the baby will be loved very much by both his or her parents,” the insider continued
