The video--featuring Psy's meme-ready dance moves--has racked up more than 815 million views since it was uploaded to YouTube on July 15. Bieber's "Baby," which has been watched more than than 803 million times since it was posted in February 2010.
"#GangnamStyle just became the most watched video @YouTube!" Psy (real name: Park Jae-Sang) tweeted on Saturday. "#History."
"Gangnam Style" already holds the title for "most liked" video in YouTube history with more than 2 million "likes," according to the Guinness Book of World Records, which officially recognized the achievement in September. The video for LMFAO's "Party Rock Anthem" is a distant second with more than 1.6 million "likes." Bieber's "Baby" is no. 3 in that category.
But true Beliebers, fear not: The 18-year-old pop star is not taking the "most viewed" loss lying down, tweeting a shirtless picture from the gym for his 30 million Twitter followers.
