In an interview for her upcoming film "Our Brand Is Crisis", the Oscar-winning actress said that there's only one adopted child in her household, reported Ace Showbiz.
"There is only one adopted child in my household and his name is Louis," she said.
"If I had a second adopted child, everyone would be hearing about it. I would be loud and clear and say, 'Yes, I have officially adopted a second child.' Right now, Louis must be it."
The "Gravity" actress, 51, really loved her five-year-old son Louis so that she wanted to film in a place that would be beneficial for her son.
