Another milestone was reached for South Korean rapper Psy, whose global hit music video "Gangnam Style" reached one billion hits on YouTube.
It's the first time any video has reached the ten digit hit count in the history of the website. Eager fans could track the count in real time on billioncountdown.com.
Last month Psy took away the crown for "most watched video on YouTube" from his record label mate Justin Bieber.
His infectious horse riding spawned countless parodies across the world and he had many galloping sessions with celebrities such as Britney Spears and U.N. Secretary-General Ban Ki-moon.
Recently the 34-year-old rapper performed for U.S. President Barack Obama at a Christmas celebration.
