The video pokes fun at the consumerism of Gangnam, an affluent suburb of the South Korean capital Seoul.
It holds the Guinness World Record for the most "liked" song ever - currently with a little under 5.4m likes on YouTube.

Bieber's manager Scooter Braun was the first person in the US to tweet a link to the Gangnam Style video."
