South Korean artist Psy continues to be on a roll as his record-busting Gangnam Style video reached over 1.3 billion hits as of Valentine's Day. He is currently on an Asian and Oceania tour and just finished a concert in Malaysia, will have a one-day concert next week in the Philippines and five concerts in Australia in March.

Within a few month of the release of his sixth album, which contained his megahit Gangnam Style, that phrase was already entered in the Urban Dictionary as the word of the day on Sept 12, 2012. The Web site said that Gangnam Style is actually a Korean neologism mainly associated with upscale fashion and lavish lifestyle seen and trendsetters in Seoul's Gangnam district.

Gangnam is the most affluent part of the South Korean capital city's metropolitan area.

On Thursday, YG Entertainment announced the release of Psy stamps in 22 postal stations around Seoul, beginning Feb 18. This development makes him the first YG artist to have his own stamp set as differentiated from ordinary stamps.

Psy must be doubly celebrating because a second version of Gangnam Style is also becoming a monster hit in YouTube with about 280 million hits so far. The second version features Psy singing his signature song with sexy Korean singer Hyuna.

Hyuna, 20, fits the sexy lady lyrics of the song. She is a member of the Korean girl group 4Minute and was a former member of another girl group, Wonder Girls.

The second version of Gangnam Style is fifth on the top 10 list of YouTube hits by views and a third version on eighth spot. Here is the list and hits as of Feb 14, 2013.
