This could make family dinners a tad awkward.
Mark Zuckerberg's sister, Arielle, is now a Google employee, following the search engine giant's acquisition of Wildfire Interactive this week.
Arielle's blog lists her occupation as the junior product manager for the social media marketing firm. Here's a photo of Zuckerberg's sister:
Arielle previously offered constructive criticism of her brother's company's site, which just went public this summer, and its overhaul last fall.
Arielle's not the only Zuckerberg sibling in the business, either. Randi Zuckerberg, the former director of marketing for Facebook, left last August.
Randi Zuckerberg is now an executive producer for Silicon Valley, a Bravo show that is controversially bringing Hollywood voyeurism to tech.
Randi tweeted about Arielle's move on Tuesday, teasing Mark a bit in the process. The Zuckerberg siblings also have another sister, Donna.
