NEW YORK - K-pop band BTS previously worked with American rapper Megan Thee Stallion on a remix of their hit single, Butter, but they had not met in person - till now.

On Tuesday (Sept 21), the 26-year-old posted on social media several photos of her meet-up with the Korean group, writing: "It's Thee HotGirl Coach and BTS."

The band posed with Megan in the first photo, with Jimin and J-Hope joining her in sticking their tongues out in the second picture.

In another photo, BTS played with Megan's pet dog.

The Butter remix featuring Megan was released on Aug 27. The release was initially held up by her record label, but a judge in Texas later ruled in her favour.

BTS were in New York for the United Nations (UN) General Assembly to promote the Sustainable Development Goals and as special envoys of South Korean President Moon Jae-in.

The pop stars filmed a music video of them performing their song, Permission To Dance, in the UN headquarters and visited the Metropolitan Museum of Art in New York with South Korean First Lady Kim Jung-sook.
