"Gentleman," the new hit single by South Korean rapper Psy, has set a Guinness world record as the most-watched online video in a single-day, according to the Guinness Web site.

   "Gentleman" became the most-viewed online video in a 24-hour period when it drew 38.4 million hits on YouTube on April 14, the second day of its release, the Web site said in an article posted on Thursday (local time).

   "Proving that 'Gangnam Style' was far from a one-hit-wonder, South Korean sensation Psy has secured another GUINNESS WORLD RECORDS title with his follow-up single, 'Gentleman,' which is the Most viewed video online in 24 hours," the article said.

   The new video had gained more than 255 million hits as of 4 p.m. Tuesday. 

   It marks the fourth Guinness world record won by the 35-year-old rapper. His previous global hit "Gangnam Style" earned him three Guinness titles -- the most-viewed video online, the most "liked" video online and the first video to receive one billion views. The video has now been viewed more than 1.5 billion times.

   The article noted that the success of "Gentleman" is more immediate than that of its predecessor, reaching 100 million views in barely four days, compared to the almost two months it took "Gangnam Style" to cross the same threshold. (Yonhap)
