Psy - the South Korean rapper behind the most 'liked' YouTube video of all time - has topped the UK singles chart with Gangnam Style.
The pop track broke into the Top 40 two weeks ago at number 37, four weeks after its release, and has been climbing steadily since ending up at number three in last week's chart.
Irish band The Script were down to number two with Hall Of Fame, featuring will.i.am from the Black Eyed Peas, while US rapper Flo Rida rounds off the top three with I Cry.
In Australia, Psy has overtaken Guy Sebastian's Battle Scars to take out the No.1 spot on the ARIA singles chart.
The catchy tune by South Korean pop star Psy has knocked Guy Sebastian's Battle Scars from the top spot to No.2.
Psy's chart-topping success in Australia now equals that enjoyed in his native South Korea, Canada, New Zealand, Denmark and the UK.
The video that accompanies Gangnam Style had amassed more than 334 million views on YouTube as of October 1.
The 34-year-old, whose real name is Park Jae-sang, is popular in his native South Korea - and now worldwide - for his humorous videos and stage performances.
Psy, who has already released six albums in his homeland, taught Britney Spears his dance moves on The Ellen DeGeneres Show last month.
His Gangnam Style video has been shared on the web by celebrities including Spears, T-Pain, Katy Perry and Tom Cruise.
The song is inspired by Gangnam-gu, one of the 25 local government districts, or gu, which make up the city of Seoul.
It has prompted a series of spoof videos - one of which saw a group of US lifeguards lose their jobs.
More than a dozen guards in the Californian city of El Monte were sacked after producing Lifeguard Style.
A Facebook page saw hundreds of comments being left in their defence - with Psy himself among their supporters.
The rapper told MTV: 'What did they do? They weren't wrong? I think it was off duty - that's what I heard. They can be more flexible to each other.'
WKRC-TV said supervisors in the Parks Recreation Division called in the lifeguards and asked them to review pages from a staff manual about violations of city property before firing them.
Since then, more than 17,000 people have signed up to support the performers via their Facebook page Bring Back The 14 El Monte Lifeguards.
Mayor Andre Quintero admitted Lifeguard Style was a 'very good parody'.
But he added: 'If these employees wanted to produce a video for their own enjoyment and memories they could have asked for permission and shared the video with their family and friends using a medium that is less public.'
