It's 2013! Check out how some of the biggest music stars in the world kicked off the new year in style.
PSY Joined By MC Hammer For "Final" 'Gangnam Style' Performance In Times Square - Video
Watch the K Pop sensation wow revellers in New York with what could be one of his last performances of the song.
PSY was joined by MC Hammer as he performed 'Gangnam Style' during the New Year celebrations in Times Square, New York.
The performance possibly marked the last time fans in the US will see the K-Pop star perform the track after he suggested ahead of his appearance that it was time to move on.
"The song became too popular, and so you start to have some concern about its life period," he told MTV News.
"I'm really working hard on a new single right now, and I'm not saying ['Gangnam'] is ending on 'Dick Clark' — I still have a lot of invitations to perform it ... I'll be in Paris, and in February I got invited to perform in China, and I've still got to do promo.
"So let me say that in America I need a new single because 'Gangnam Style' got too popular, so I've got to write a new single."
