Robert Downey Jr. got a sequel to his movie Due Date, but this one won’t be released in theatres.

The actor and his wife Susan just welcomed a baby boy, Exton Elias Downey.

According to People magazine, Robert’s family is healthy and everyone couldn’t be happier to welcome the new addition.

The 46-year-old accidentally revealed they were expecting a boy on the Tonight Show With Jay Leno, and according to the actor, his wife wasn’t happy…

He said if he ruined the surprise of the name Exton, Susan would have “lopped his head off with a machete.”

Well, like his character Sherlock Holmes, he got the clue.

Iron Man was able to keep the name an iron clad secret till now.
