The "Sherlock Holmes" actor welcomed a daughter with his ex-girlfriend, singer-songwriter Catherine Harding, according to People.
"I can confirm the arrival of Jude Law and Catherine Harding's daughter," a representative for Law said in a statement on March 17. "Both are delighted and continue to ask that their privacy and that of their child be respected."
In addition to his new daughter, Law also has three kids with his ex-wife, Sadie Frost, and one daughter with Samantha Burke, the site reports.
"Whilst they are no longer in a relationship, they are both wholeheartedly committed to raising their child," Law's representative said in the statement.
