Facebook isn’t the only awesome thing Mark Zuckerberg co-created!
The tech mogul's daughter, Max, whom he shares with wife Priscilla Chan, turned 1 on Wednesday, and the proud father took to his social media platform to share a snapshot of the special day.

"I can't believe it's been a year! And she kissed me on the cheek for the first time yesterday," the 32-year-old billionaire wrote in the post. "Here's to many more years of happiness and health for Max and all children around the world."
While this was his daughter's first birthday celebration, Zuckerberg hopped on Facebook back in October to celebrate another important milestone -- her first word.
"Max loves Beast," the 32-year-old Facebook co-founder wrote alongside a picture of his little girl petting their pet Puli. "Her first word: dog."
