Apparently Bublé has a big gig at London's O2 Arena this Saturday, which makes the timing of this AR experience very convenient. Almost as if some people in marketing did it on purpose or something. O2 claims that this is the first time anyone has done this sort of thing with a musician, and the point of the app is to have Bublé appear on screen in a puff of smoke and interact with fans.
Bublé lovers can pose for selfies with the singer, while the phone user alters his position to get the perfect shot. Fans can also interact with the singer as he beckons them over, kisses them, or gets down on one knee to propose.
