Justin Bieber may have only just touched down in Seoul, but sources tell IdolWow! he's already been hanging out with PSY.
A source says that Bieber arrived in Seoul today, October 8, with his manager Scooter Braun, who also looks after PSY. "They checked into the hotel, had some rest and then went out into Gangnam area," says the insider. "It was there they met PSY and some others for dinner."
Apparently PSY -- who returned to Korea from Los Angeles last month to spend time with his family -- made plans to meet the 19-year-old singer some time ago to discuss a project.
Bieber is in the country for his Believe concert on Thursday and is rumored to be collaborating with G-Dragon and PSY, 35, while he's in town.

Last month he teased that fans might be seeing him onstage with the pair, tweeting: "excited to get to Korea to perform on October 10th. Maybe u will see my guys @psy_oppa and @IBGDRGN. Get the bbq ready. #BELIEVETOUR"
And while a spokesman for the "Beauty and a Beat" star refused to comment, a close source told IdolWow!: "There's a surprise we're working on. Watch this space."
