As it turns out, it's not just Justin Bieber's world.
South Korean rapper Psy's contagious hit, "Gangnam Style," just nabbed quite the impressive title from the Biebs' "Baby", becoming the most-watched YouTube video of all time.

The music video has earned about 803,761,000 views since it was first posted to the site in July. Meanwhile, the music video for "Baby" racked up 803,732,000 since it was released in February 2010, according to Billboard.
"#GangnamStyle just became the most watched video @YouTube!! #History," Psy tweeted Saturday.
Psy catapulted to international stardom this summer with the release of the hit single and music video, most recently performing the dance with Madonna at her New York City concert, and with MC Hammer at the 2012 American Music Awards.
Ironically, Psy became label mates with the Bieber in September, when he signed to Scooter Braun's Schoolboy Records.
