American talk show host Conan O'Brien said Sunday he has sung on a new track produced by the prolific South Korean musician Park Jin-young.

O'Brien shared a photo of him with Park, Korean-American actor Steven Yeun, the South Korean girl group TWICE and backup dancers on Instagram with the comment: "@SteveYeun and I got to sing on a brand new track by #Kpop king.... Get ready, #Korea!"

The photo was presumably taken after shooting the music video for Park's upcoming song Thursday. Park is the founder of a top three South Korean management agency, JYP Entertainment.

It remains to be seen whether the video's behind-the-scenes will be shown on a "Conan" episode next week.

South Korean girl group Wonder Girls, who weren't pictured, is also known to have participated in the video.

O'Brien was in South Korea from Sunday to Friday to shoot portions of "Conan."

The trip was planned, O'Brien says, because he wanted to thank a South Korean girl who sent him a box of Korean snacks in person. (Yonhap)
