Robert Downey Jr: "We're Having a Boy!"

Posted Tuesday December 6, 2011 8:46 AM GMT

Stepping out for a promotional appearance, Robert Downey Jr was spotted at “The Tonight Show with Jay Leno” last night (December 5).

The “Iron Man 2” stud looked to be having a good time as he chatted with Leno about the exciting news that he and wife Susan Downey will welcome their first child together in February.

And Robert even shared the soon-to-be-born’s gender - “We’re having a boy,” he blurted out while covering his face in pretend shame.

As his new movie, “Sherlock Holmes: A Game of Shadows” is scheduled to hit theaters on December 16th.
