Joseph Gordon-Levitt and his wife, Tasha McCauley, are getting really good at keeping secrets. The couple, who privately married in 2014, reportedly recently welcomed their first child together without anyone knowing. Sources say McCauley, 34, was able to hide both her pregnancy and the child's birth completely.

According to Us Weekly, the "The Walk" actor's wife gave birth to a baby boy over the weekend of Aug. 15. Reps for the 34-year-old actor have confirmed the child's birth but declined to give an exact date of birth for the child. Insiders told Us magazine that the baby boy, and his sneaky mama, are "happy and healthy." Few details, including what name they chose, are known at this time. 

This isn't the first time Gordon-Levitt and McCauley have pulled off a grand surprise. The couple was secretly married on Dec. 20, 2014. They went public about their relationship in September 2013, according to Us. The wedding is said to have taken place at their home in Los Angeles. It remains unclear who was in attendance at the low-profile nuptials.
