Mark Zuckerberg embraces his pregnant wife Priscilla, parents and sister in family photo

Today Mark Zuckerberg took to his FB page to share what he is thankful for this thanksgiving. He said:
Priscilla and I have a lot to be grateful for this Thanksgiving and holiday season, and family is at the top of our list. This is a big year for our little family, and we're so filled with hope for all that's ahead.
Reflecting on family, I want to share this photo Annie Leibovitz captured with my parents and sister last month. I'm looking forward to many more moments with family to come.
