South Korean hitmaker Psy has shared the behind-the-scenes of the music video for his latest single "That That" with BTS' Suga.

The nearly five-minute video posted on Psy's official YouTube page shows the "Gangnam Style" singer discussing the scenes with the crew and sharing a light moment with Suga, who also served as the producer of the single.

In one scene, Psy can be heard praising Suga as the latter joins the set for the first time. "Lookin' so good I couldn't recognize you," he tells the BTS member. He later discusses the slap scene with Suga, saying, "So I slap you first then you slap me."

Suga can then be seen giving Psy a hand following the slap. "Wow, I really went all out," Psy tells the crew.

The video also offers a peek into the filming process of the fan-favorite scene, in which Suga holds an injured Psy as they sit on a car's hood.

The video also shows Psy giving the crew instruction before going through another dance sequence with his dancers. "When Yoongi (Suga) is doing his part, I'd like him to look down but look up at the sky and cry, just drenched in sadness," he tells them.

At some point in the video, Psy and Suga pose before the camera while standing on top of the car. Suddenly, a flock of birds flies above them, adding more excitement to the scene.

A crew member then exclaims, "Whoa, the flock of birds!" Aware of how the birds' presence has taken that particular scene to a whole new level, Psy remarks, "Wow! The flock of birds is awesome."

Fans took to the video's comments section to share their reaction to the behind-the-scenes.

"Loved seeing two legends in one frame. The making of the MV was so wholesome, their smile clearly shows how much they enjoyed filming it with each other," a fan wrote.

"Everyone seemed to enjoy the filming, that's why the joy is so contagious in the mv, paired with the awesome song!" another noted.

Meanwhile, some fans commended Psy for his hard work.

"You can tell how much effort is put into PSY's work, it's always a high quality production. This is an absolute earworm & it's in my head 24/7," a fan said.

"That That" was released on April 29 and is the first single from Psy's new album, "Psy 9th."
