This is a stunning photo of Priscilla. I love her expression: intense yet kind, fierce yet loving, leading yet always supporting others. Thank you to Annie Leibovitz for capturing her spirit so beautifully.

Proud parents-to-be. Mark Zuckerberg and his pregnant wife, Priscilla Chan, posed for a black and white photo shot by famed photographer Annie Leibovitz — and it's beyond gorgeous. The Facebook co-founder and CEO shared the intimate portrait on the social media platform on Wednesday, Nov. 4.

"This is a stunning photo of Priscilla. I love her expression: intense yet kind, fierce yet loving, leading yet always supporting others," Zuckerberg,31, wrote. "Thank you to Annie Leibovitz for capturing her spirit so beautifully." In the pic, Zuckerberg sweetly stood behind Chan, 30, and cradled her growing baby bump.

Last month, Zuckerberg also shared a behind-the-scenes moment from the photo shoot. "Here's a fun shot of the amazing photographer Annie Leibovitz taking photos of me, Priscilla, my parents and sister backstage after I spoke at the Vanity Fair summit this afternoon," he wrote. "I'll share Annie's actual photos of us in a few days after she picks the best ones."

As previously reported, Zuckerberg and Chan married in a lavish May 2012 wedding after dating for nine years. They announced this past July that they are expecting their first child together — a baby girl.

"We've been trying to have a child for a couple of years and have had three miscarriages along the way. You feel so hopeful when you learn you're going to have a child. You start imagining who they'll become and dreaming of hopes for their future," Zuckerberg wrote via Facebook at the time. "In today's open and connected world, discussing these issues doesn't distance us; it brings us together. It creates understanding and tolerance, and it gives us hope."
