In the flesh: The sky's the limit when it comes to Samsung's VIP list. Zuckerberg takes the stage with D.J. Koh, Samsung mobile communications business president.

BARCELONA: In a surprise development, Facebook CEO Mark Zuckerberg showed up unannounced at the Samsung Unpacked event and promptly stole the show.

The media was asked to put on the Samsung Gear VR headset for a virtual reality presentation on the Galaxy S7, S7 Edge and the Gear 360, but when the journalists took it off, they were greeted with the sight of the social networking titan in his signature gray T-shirt and blue jeans.
