The strip tease no one wanted to see has happened (as promised). 'Gangnam Style' star Psy has performed half-naked during a show in Seoul. See the video below.

The rapper previously promised to perform topless if his single hit No.1 in America. It didn't, but he got his kit off all the same.

"If I do become number one on Billboard, I'd dare to dance half-naked in front of a large crowd of people," he said at a press conference in his hometown of Seoul at the end of September. "I would pick a place, preferably in front of Seoul City Hall."

Psy became the first ever Korean star to top the UK charts when 'Gangnam Style' took the top spot on Sunday (30 September, 2012).
