Mark Zuckerberg and Priscilla Chan Are Having Another Baby Girl

Mark Zuckerberg and his wife, Dr. Priscilla Chan, are expecting a second baby girl. Their first daughter, Max, was born in December 2015, and was accompanied by a sweet announcement on Facebook (naturally). And the second pregnancy is no different.

The Facebook CEO announced the happy news on—what else?—his Facebook page Thursday, and said that he and Chan weren't sure about the future of their family given their difficulties conceiving Max. He also wrote a moving message about the importance of sisters, and posted adorable old photos of both parents as kids with their own sisters.

"I grew up with three sisters and they taught me to learn from smart, strong women," he wrote. "We are all better people because of the the strong women in our lives -- sisters, mothers and friends. We can't wait to welcome our new little one and do our best to raise another strong woman."

Recently, Chan and Zuckerberg have been traveling the country to follow up on Zuckerberg's New Year's resolution to visit every state in the U.S. They recently took little Max to visit a Mardi Gras parade in New Orleans:

But most importantly, it remains unclear what Beast, the Chan-Zuckerberg family's adorable mop of a dog, thinks of this new development. He seems pretty OK with it though.
