Where wouldn't you expect a Zuckerberg to land? Google is probably at the top of that list.
But Tuesday, Google (GOOG, Fortune 500) officially "friended" Facebook CEO Mark Zuckerberg's sister, Arielle Zuckerberg, when it acquired Wildfire, the social ads marketing firm she works at.
"Congrats Wildfire! There are officially now more Zuckerberg family members working for Google than Facebook! #awkward ;)," sister Randi Zuckerberg blasted off in a tweet, alluding to the possibility that another member of their family is a Google employee.
Google declined to comment on whether all of Wildfire's 400 employees would joining the company following the acquisition.
Arielle Zuckerberg works as a junior product manager at the Redwood City, Calif.-based company, which helps marketers engage their audiences using social media.
"It's a platform for brands to manage their pages, apps, tweets, videos, sponsorships, ads, promotions and more, all in one place," Google product management director Jason Miller wrote on the company's blog. "We're looking forward to creating new opportunities for our clients to engage with people across all social services."
Arielle Zuckerberg isn't the only sibling making headlines for career moves. In April, Randi Zuckerberg announced plans to team up with Bravo for a reality television series based on Silicon Valley entrepreneurs. She left Facebook last year to start her own media company.
Facebook (FB), which had a rocky debut into the public market in May, competes fiercely with Google, which is trying to expand its social-networking clout.
