Last week, Facebook founder Mark Zuckerberg and girlfriend Priscilla Chan adopted a dog named Beast. He already has 65,300 Facebook fans and a photo of himself posing with a visiting dignitary.

Consequently, the paparazzi are wising up to Beast's star potential.

Yesterday, Mark, Priscilla, and Beast exited the house around the same time. Mark's pajamas drew some interest.

But Beast was clearly the main attraction. Our photo agency ended up with three shots of Mark, five of Priscilla and Beast, and one close-up of Beast, the preternaturally adorable being that humanizes the chilly power couple. In other words, Beast : Silicon Valley :: Suri Cruise : Hollywood. He'll be prancing around in high heels in no time. [Images via Pacific Coast News]
