Justin Bieber no longer holds the title of having the most-watched YouTube video of all time, after he was surpassed Saturday by South Korean pop-sensation Psy.

‘Gangnam Style’ is now YouTube’s most-watched video of all time, with more than 803-million views putting it ahead of Bieber’s hit song, ‘Baby’.

The 34-year-old Psy has rocketed to fame since Gangnam Style became a worldwide hit following its release in July.

Earlier this month the song passed Jennifer Lopez’s dance hit ‘On the Floor’ for second place, before overtaking ‘Baby’ Saturday.

Psy’s song, which talks about an upscale neighbourhood in South Korea called ‘Gangnam’, has topped charts all around the world and its corresponding dance has become a worldwide fad.

The quirky star, whose real name is Park Jae-Sang, has won adulation in his homeland for the global hit and was this month awarded one of South Korea’s highest cultural honours, the Okgwan Order of Cultural Merit.
