Robert Downey, Jr. and wife expecting second child together

Actor Robert Downey, Jr. is set to become a father for the third time.

The Iron Man star, 49, will welcome a daughter with wife Susan Downey in November (14), according to a brief message posted on his Twitter.com page on Wednesday (09Jul14).

He writes, "Yo. Susan. Me. Baby. Girl. November. Scorpio?"
