Mark Zuckerberg and his wife Priscilla Chan have another baby on the way.

The 38-year-old Facebook co-founder shared via Instagram that his 37-year-old wife is pregnant with their third child.

“Lots of love. Happy to share that Max and August are getting a new baby sister next year!” he wrote alongside a picture of themselves as he placed his hands on Chan’s stomach.

The couple is also parents to two daughters- Maxima Chan Zuckerberg and August Chan Zuckerberg born on November 30, 2015, and August 28, 2017, respectively.

Mark Zuckerberg and Priscilla Chan first met in 2003 while attending Harvard University. They got engaged after he popped the question in 2011. The news was accidentally broken by Bill Gates during a Daily Mail interview during which he referred to Chan Zuckerberg’s “fiancée.”

The couple eventually married on May 19, 2012.

Speaking of how fatherhood had changed his life, the social media founder shared, “Having kids does change how you think about the world in a pretty dramatic way. I used to have meetings that ran really late. But now, I make sure that three times a week, I’m home to give [Max] a bath. The thing that I’m most proud of and the thing that brings me the most happiness is my family.”
