BTS’ Jung Kook Shows Off Washboard Abs in Smoldering Campaign for Iconic Brand: ‘Good to Be Back’

Jung Kook’s new Calvin Klein campaign is so steamy, it could melt butter. 

The BTS star’s latest campaign with the fashion brand launched Tuesday (Oct. 28), complete with a series of eye-catching photos shared with Billboard as well as new ad spot. In the video, Jung Kook zips through city streets on a motorbike before strutting down a red hallway, staring down the camera. He also performs some of his million-dollar dance moves before retiring to a high-rise apartment, in which he hangs out with his shirt unbuttoned to show off his Calvins’ iconic waistband.  

The chic, dynamic photos — which were shot by Mert Alas — show the K-pop phenom smirking into the lens while modeling a handful of different looks, including a denim set and white T-shirt, the sleeve of which he lifts to show off his tattoo-covered arm. 

“I know that my fans have been eagerly waiting for this return, and it feels so good to be back in the brand’s iconic denim,” Jung Kook said of the campaign in a statement. 

Jung Kook has been working with CK for a few years now, debuting his first collaboration with the company in March 2023. A few months later, he once again posed for the brand, sporting shaggy rock-star hair with his washboard abs on full display. 

In February 2024, the performer gave ARMY a late Valentine’s Day present by way of another smoldering Calvin Klein shoot set at Grand Central Station in New York City. 

The new campaign comes as Jung Kook and his bandmates are preparing to make an epic comeback in 2026. BTS has spent the past couple of years working on solo projects and fulfilling their service requirements to the South Korean military, with Jung Kook releasing single “Never Let Go” in 2024 before he was discharged this past June.
