Rapper Psy has become the first South Korean musician to make it to number one in the UK with his single 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, ending up at number three in last week’s chart.

The video that accompanies the single has amassed more than 335 million views in just two months and became the most “liked” video of all time on YouTube.

Psy, who is already an established star in South Korea having released six albums, taught Britney Spears his dance moves on US TV show Ellen earlier this month.

Psy had vowed to perform his “Gangnam Style” hit topless if it reached number one in the US.

His video, ‘Gangnam Style’, was posted on YouTube in July and has since had 335 million views. The number of ‘likes’ has hit over two and a half million, which is a record for a video posted on YouTube.
