On August 29, PSY gave an interview to SBS “One Night of TV Entertainment” and revealed that he’s given Justin Bieber a drinking lesson during his recent trip to the U.S.

After saying that a lot of discussion went back and forth regarding his U.S. debut, PSY jokingly said, “One thing that you should be warned of is the fact that I taught Bieber how to drink So-Maek.” So-Maek is the abbreviated word for a Soju-Maekju (beer in Korean) cocktail, which is a pretty common drink in Korea.

He added, “We haven’t really finalized on the details yet, so I’ll let you know what happens as soon as a decision is made.”

PSY later added, ‘Yang Hyun Suk (chairman of YGE) treats me differently now. In the past, whenever I called him, he would just say, ‘What?’ or ‘Why?’ But now, he answers my call saying, ‘Hey, CNN brother~.’”

PSY will be flying back to the U.S. in September to resume talks with Justin Bieber and his representative Scooter Braun. Stay tuned for more updates!
