Jude Law is quite the super-sleuth when it comes to helping solve mysteries as Dr. John Watson in the upcoming Sherlock Holmes film—but when it comes to playing the role of doting dad, however, Jude can't seem to remember his lines.
Speaking with David Letterman Thursday, Law told Letterman he had a fun beach vacation planned for his children this holiday season.
When Letterman asked him how many kids he has, Law responded, "Three."
Law does have three children with his former wife, Sadie Frost, but -- Oops! -- there's a fourth he forgot to mention: baby Sophia, who was born September 22 to Law's one-time fling, model Samantha Burke.
Hopefully, he remembers to keep those checks coming. Sherlock Holmes opens in theaters Christmas Day.
