Mark Zuckerberg and his wife Pricilla Chan are expecting a second daughter!

The social media tycoon made the announcement on his website today: “When Priscilla and I first found out she was pregnant again, our first hope was that the child would be healthy,” he wrote. “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.”

Mark and Pricilla already have a 1-year-old daughter named Max. So baby number two is sure to grow up side-by-side with her — how cute is that!

Pricilla suffered from three miscarriages before giving birth to Max, so to be expecting another daughter is true blessing.
