There's no hiding who Max Zuckerberg's favorite member of the family is.

Mark Zuckerberg's 1-year-old daughter with Priscilla Chan uttered her first word — and it wasn't what you'd expect.

Max went with "dog" to showcase her love for Beast, the family's Hungarian sheepdog.

The 32-year-old Facebook CEO took to his social networking site, of course, to share the news, along with a sweet photo.

"Max loves Beast. Her first word: dog," he wrote on Facebook.

Even though her first words weren't the conventional "mom," "dad" or even "Facebook," her parents are "over-the-top proud of everything she does," Chan told Savannah Guthrie in an exclusive interview last month.

"She could be eating. She could be spitting. She could be sleeping. She could be just smiling and we're, like, ‘Oh, isn't that special?'" Chan said.

While Beast has become a social media star, garnering more than 2 million Facebook fans, Zuckerberg and Chan don't plan on giving their daughter that same exposure.

"Max will have her own Facebook page, but she'll need to wait till she's 13 when she's old enough to have one," Chan told Savannah, referring to minimum age of users who want to create an account. "She has to follow the rules."
