Sandra Bullock is now a proud mother of two. The actress revealed she adopted a 3-year-old daughter named Laila on Wednesday. 

In an interview with People, Bullock, 50, revealed that she had adopted Laila from Louisiana, who had been in foster care. Bullock kept the adoption secret until the process was complete. Laila is Bullock's second adopted child. The "Our Brand is Crisis" star adopted her now 5-year-old son Louis in 2010.

"When I look at Laila, there’s no doubt in my mind that she was supposed to be here," Bullock said. "I can tell you absolutely, the exact right children came to me at the exact right time."

The film star's decision not to show her daughter's face in photos, as first noted by TMZ, appears to be for privacy reasons. Bullock told People trying to keep Laila a secret was similar to "witness protection." In her interview, Bullock said a photographer snapped a picture of her with Laila and Louis during an emergency room visit, something the actress said she had legally agreed to prevent from happening to her daughter.

"Most foster children are in foster care because they were taken from their birth homes under tragic circumstances and the last thing I wanted was to bring more harm to her because of the nature of my job,” she said.

The actress said Louis and Laila get along and have already formed a bond. Three years ago she got the idea of making the family bigger, which she credits to Louis.

At the premiere of "Our Brand is Crisis" in October, E! Online reported that a journalist asked Bullock if she had adopted a second child. The actress insisted she hadn't, which is likely because the adoption process was not complete. 

"There is only one adopted child in my household and his name is Louis. If I had a second adopted child, everyone would be hearing about it." Bullock said. "I would be loud and clear and say 'Yes, I have officially adopted a second child.' Right now, Louis must be it."
