Facebook founder Mark Zuckerberg to be a dad

Facebook founder Mark Zuckerberg is set to become a first-time father.

The tech entrepreneur took to the social networking blog on Friday (31Jul15) to announce his wife, Priscilla Chan, is pregnant with a baby girl.

He writes, "This will be a new chapter in our lives. We've already been so fortunate for the opportunity to touch people's lives around the world - Cilla as a doctor and educator, and me through this community and philanthropy. Now we'll focus on making the world a better place for our child and the next generation."

Zuckerberg, who was portrayed by actor Jesse Eisenberg in 2010 movie The Social Network, also revealed their path to parenthood hasn't been easy.

The 31 year old continues, "We've been trying to have a child for a couple of years and have had three miscarriages along the way...

"We hope that sharing our experience will give more people the same hope we felt and will help more people feel comfortable sharing their stories as well.

"Our good news is that our pregnancy is now far enough along that the risk of loss is very low and we are very hopeful."

The couple wed in 2012.
