Mark Zuckerberg can't wait to be a daddy and wants the entire world wide web to know it!
The precious pic — taken by Annie Leibovitz — is an incredible black-and-white portrait of the cute couple, featuring the social media guru with his arms wrapped around his lovely lady, who is also holding her growing belly!
As if this image couldn't be any more adorable, the 31-year-old captioned the photo by gushing about his main squeeze, saying:
"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."
UGH. We can't. Our hearts. They're melting from CUTENESS OVERLOAD.
Congratulations to FB's first family! We can't wait to see your little one!
