South Korean rapper Psy's music video, "Gentleman," surpassed the 600 million view mark on YouTube Friday.

   The video has attracted more than 600.40 million hits since it was released in April, according to the video-sharing website.

   The milestone was reached more than four months after the video broke the 500 million mark on July 31.

   "Gentleman" had set a world record as the most-watched online video in a single day upon its release, breaking 100 million views in the shortest period of time in Youtube's history.

   The singer's 2012 global mega-hit, "Gangnam Style," has garnered 1.84 billion views.

   Psy, meanwhile, is scheduled to hold concerts in Seoul on Dec. 20-22 and Dec. 24 before a combined audience of 60,000. Sources say he may perform a new song during the concerts. (Yonhap)
