Itâ€™s a boy for Robert Downey Jr.!
Wife Susan delivered son Exton Elias Downey at 7:24 a.m. on Tuesday, Feb. 7 in Los Angeles, his rep confirms to PEOPLE.
â€œEveryone is healthy and they couldnâ€™t be happier,â€ a friend of the couple says.
Baby boy weighs in at 7 lbs., 5 oz., is 20 inches long and joins big brother Indio, 18, Downeyâ€™s son from his previous marriage.
After announcing the pregnancy in August, the Sherlock Holmes: A Game of ShadowsÂ star, 46, revealed the sex of the baby on national television, much to his producer wifeâ€™s (feigned) chagrin.
â€œI could never really stay mad at him, but I can tell you it genuinely wasnâ€™t something we planned to reveal,â€ Susan, 38, later explained.
Thankfully, her husband â€” who will next star in The Avengers â€” did manage to keep quiet about their name choice.
â€œIf I told you the name, then she would lop off my head with a machete,â€ joked Downey.
