Korean rapper Psy said Saturday lots of good things look likely to happen for him, returning from a 10-day trip to the United States to discuss working in collaboration with Justin Bieber's management agency.

During the visit, Psy met with Bieber's manager, Scooter Braun.

The K-pop singer was reportedly offered a chance to release his hit single "Gangnam Style" in the United States.

"Nothing has been decided yet," Psy told reporters upon arriving at Incheon airport. "Lots of more interesting things will likely happen in the future," the singer-rapper said, without elaborating.

The singer, whose given Korean name is Park Jae-sang, then evoked cheers from reporters and his fans by performing his famous horse-riding dance as in his hit song "Gangnam Style."

His agency, YG Entertainment, said the 35-year-old singer will visit the U.S. again early next month as soon as he finishes already scheduled appearances in his home country. YG said there will soon will be good news about Psy but gave no further details.

"Gangnam Style" has drawn wide media attention in the last few weeks, maintaining its No. 1 position for four weeks on Billboard's K-pop Hot 100 chart.

The music video for "Gangnam Style" has racked up almost 50 million views on YouTube and topped the U.S. iTunes music video chart, beating out Bieber, on Tuesday. (Yonhap News)
