Mark Zuckerberg and his wife, Priscilla Chan, are expecting another baby girl, the Facebook CEO announced on Thursday.
The baby will be their second child after their 1-year-old daughter, Max.
“After our difficult experience having Max, we weren’t sure what to expect or whether we’d be able to have another child,” Zuckerberg wrote in a Facebook post.
“When Priscilla and I first found out she was pregnant again, our first hope was that the child would be healthy. My next hope was that it would be a girl. I cannot think of a greater gift than having a sister and I’m so happy Max and our new child will have each other.”
After their daughter Max was born in December 2015, Zuckerberg and Chan announced their philanthropic Chan Zuckerberg Initiative to give away 99% of their wealth. They’ve since made investments in education and committed to spending billions on scientific research to cure the world’s known diseases.
