The director's girlfriend, model Jacqui Ainsley, 29, reportedly delivered a baby boy via emergency cesarean on Monday morning in London, according to the U.K.'s The Sun.
The couple, who have been dating since 2010, confirmed the pregnancy in March.
Ritchie, 42, reportedly called his ex-wife, Madonna, to share the happy news, and she sent a huge congratulatory bouquet of flowers.
The Sherlock Holmes director is already father to two sons, Rocco, 11, and David, 6 this month, from his marriage to Madonna.
The director's rep did not immediately respond to calls for comment.
