Robert Downey Jr.’s family has just gotten bigger.

According to People, Downey Jr. and his wife Susan Downey welcomed their second child together, a baby girl, in Los Angeles on Wednesday, November 5.

The Iron Man star announced the exciting news on his personal Facebook page.

“After 9 months of intensive development, Team Downey is pleased to announce our 2014 fall/winter project,” Downey Jr. joked. “Principal photography commenced 11-14 and will continue until she says, “Dad! You are embarrassing me…I’m 30, this has gotta stop.”

“Yep…Avri Roel Downey joined the party @ 3:22 a.m. on November 4th…she’s 7lbs even, spans 20 inches, and is accompanied by a variety of Susan’s traits that have seemingly overwritten my “junk DNA.” I’ll post pics here + there when I’m not too busy staring…” he added.

On Thursday, October 30, while accepting an award at the BAFTA Los Angeles Jaguar Britannia Awards in Beverly Hills, Downey Jr. spoke about his wife’s pregnancy.

“For the safety of herself and others, I firmly believe that she rigged it for me to get this thing so I’ll be distracted by the implications just long enough for her to get through labor and deliver our baby girl,” he said. “She trusts [childbirth] will be a breeze compared to developing projects with me when I’m coffeed up, when I’m an ‘idea machine.’ Or worse yet, when I’m right because ‘I made it! I’m powerful! People like me! If this is the mafia, you know, I’m an earner.’”

“Mrs. Downey, any day now when you’re in the throes of birthing, if you need to yell at me or scratch me, scratch my face or blind me, it’s fine,” he added. “Because, yes, I did that to you.”

Congrats! Robert Downey Jr. and his wife Susan Downey welcomed a baby girl! http://t.co/eKLY899ouq
