Facebook CEO Mark Zuckerberg is among the billionaire bachelors who aren't actually eligible.

He's been dating girlfriend Priscilla Chan since college, but you wouldn't have known it from his Facebook pageu00a0 until this weekend.

The 26-year-old is now officially "in a relationship." He updated his status on Sunday, remarking that it was "slightly overdue."

This follows on the heels of Zuckerberg and Chan buying a puppy together and giving it its own Facebook fan page.

Beast has attracted over 70,000 fans who have learned that Facebook's CEO can't untag himself from poop-scoop duty.

Facebook presents a quandary for many people these days is it a personal site for intimate photos and relationship news as when it first launched, or is it a professional site for connecting with colleagues and presenting a highly-groomed and curated public face to the world?

It seems like Zuckerberg is increasingly using Facebook to reveal personal information about himself from his off-the-market relationship status to photos of his dog to providing a list of his family members.
