Recently it was reported that PSY had joined Hook Entertainment.

On May 30, a source from the agency told Xportsnews, “It’s true that we’ve met with PSY. But it was not to sign an exclusive contract. I understand that [the meeting] was to discuss other work. Our agency already had friendly relations with PSY so the two parties met naturally.”

Other artists at Hook Entertainment include Lee Seung Gi, Lee Seo Jin, and Lee Sun Hee, while PSY recently left YG Entertainment after his contract there concluded.
