Campaign Viral Chart: Bieber does viral double

The ad for Bieber's fragrance, Girlfriend, follows weeks of teaser ads in which the viewer is put in the position of the young singer's girlfriend.

The ad, created by BBH LA, is the second most-shared ad this week and joins Bieber's appearance in this year's Macy's Christmas ad, which debuted in last week's chart.

Last week's most-shared video, "dumb ways to die", created by McCann Melbourne for Melbourne's Metro Trains, adds a further 577,530 shares and continues its run on top.
