Robert Downey Jr. having a baby girl, is ‘certain’ women run world

Robert Downey Jr. is singing the praises of “Iron Women� out there: The “Iron Man 3� actor and his wife, Susan, are having a baby girl.

Downey made the announcement Wednesday on social media, sharing the plaudit along with the news that he’ll be welcoming a baby girl in November.

“Um. I don’t know if it’s a ‘man’s world’, but I’m certain women run it,� the 49-year-old wrote on Facebook. “Susan and I are therefore delighted to announce we are expecting a baby. Girl. November. rdj�

He also made another version of the announcement on Twitter.

“Yo. Susan. Me. Baby. Girl. November. Scorpio?� he tweeted.

It’s the third child for the “Chef� star, who has a son named Exton Elias Downey with Susan, 40. He also has a 20-year-old son, Indio Falconer Downey, from a 14-year marriage to Deborah Falconer that ended in 2004.

Indio made headlines late last month after being arrested on suspicion of drug possession.

The Oscar-nominated actor and his second wife met on the set of his 2003 flick “Gothika,� on which she was a producer. They wed on Aug. 27, 2005, and welcomed Exton on Feb. 7, 2012. In addition to many other projects, Susan Downey is a producer on her husband’s “Sherlock Holmes� movies.

Downey joked with Jay Leno in December 2011 that his wife’s first pregnancy had been “tougher� on him than on her.

“Just the hormones and the mood stuff and the nausea, and the whole thing,� he quipped, also blurting out that they were expecting a boy.
