Facebook founder Mark Zuckerberg and his wife Priscilla Chan are becoming parents for the third time.
With a photo showing his hand on the 37-year-old's stomach, the New Yorker announced the upcoming baby on Wednesday.
"Lots of love," Zuckerberg wrote on Instagram, revealing that Chan is expecting another daughter.
The former pediatrician, who met her future husband almost 20 years ago at a party at Harvard University, gave birth to their first daughter, Maxima, in December 2015.
Daughter August followed two years later.
As the couple revealed at the time, their second pregnancy came as a surprise after Chan had previously suffered multiple miscarriages.
Zuckerberg, who walked down the aisle ten years ago with the daughter of Chinese refugees, is considered a family man.
"When you have children, your perspective on the world changes dramatically," the billionaire said after the birth of his daughter August in a speech at the North Carolina Agricultural and Technical State University in Greensboro.
