Psy has held onto the title for quite some time, but now it's time for someone new to take the throne.
It's been 5 years since it's release and it's accumulated 2.896 billion views, which had made it the most viewed Youtube video of all time.
But, Charlie Puth and Wiz Khalifa's emotional 'See You Again" has overtaken it, with 2.903 billion views- the track was a tribute to the late Paul Walker from the Fast and Furious Series. It was only released in 2015!
