South Korean superstar PSY (real name: Park Jae-Sang) received his Guinness World Records certificate in London today for his hit "Gangnam Style", which became the most "liked" video in YouTube history last month.

PSY received the prestigious award during an interview with Scott Mills, who championed the single, at BBC Radio 1.

"I'm honoured," said PSY. "This is the first certificate I've ever had… I didn't get one at school."

The online sensation has only been available to view since the 15th of July but as of today has been 'liked' 4,911,081 times, which puts its competitors in the shade; LMFAO's Party Rock Anthem has accumulated 1,574,963 likes, Justin's Bieber's Baby (1,327,147 likes) and British pop star Adele's Rolling in the Deep (1,245,641 likes).

"We're pleased to present his official certificate to such a global phenomenon," said Guinness World Records Editor-in-Chief Craig Glenday, who presented the certificate at the radio studio. "Gangnam Style is an infectious, joyous song that has brought a smile to the faces of a tenth of the world's population, and the result is that it's the most liked video of any kind in the history of YouTube!"

Gangnam Style, PSY's most successful single to date, is the most viewed K-Pop video on YouTube, and also marks the first time a South Korean artist has topped the iTunes charts.
