South Korean rapper PSY's "Gangnam Style" has become the most watched video in YouTube history.
On Saturday, the video had been viewed 805 million times, surpassing Bieber's "Baby," which had 803 million views, the YouTube trends blog reported.
The 34-year-old rapper has become a global phenomenon with his catchy song and signature horse-riding dance moves.
"Gangnam Style" gained an audience outside of PSY's native South Korea in early August and had a meteoric rise to the top spot.
It doesn't seem that people are tiring of it. According to YouTube, the video is watched between 7 million and 10 million times a day around the world, from India to Brazil to the United States.
Bieber had held the record since July 2010 when he unseated Lady Gaga's "Bad Romance."
