A rep for Samantha Burke — the 24-year-old aspiring actress whom Jude Law met while filming Sherlock Holmes in New York City last year — confirms to PEOPLE that her client is ” overwhelmed with joy” at the birth of her daughter, Sophia, on Tuesday, September 22nd. Sophia weighed in at 5 lbs., 12 oz.

Jude, 36, who has three other children with ex-wife Sadie Frost, is currently appearing in a Broadway production of Hamlet, now in previews.

Jude’s rep confirmed the pregnancy in a statement released last July after reports surfaced in the media that Samantha was expecting.
