"Elvis" director Baz Luhrmann shared a series of clips on his Instagram Stories on Monday, July 18, to thank G-Dragon for his rendition of one of Elvis Presley's iconic songs, "Can't Help Falling in Love." The Australian filmmaker has nothing but good words for the Big Bang member, agreeing that he's indeed the King of K-Pop.

G-Dragon surprised everyone when he dropped his cover of "Can't Help Falling in Love" on YouTube on Sunday, July 17. After weeks of hinting at a collaboration with Baz Luhrmann for his latest film "Elvis," led by Austin Butler, fans finally had a full look of it.

The "Moulin Rouge" and "The Great Gatsby" filmmaker said the K-pop idol had "put his own colors" on the song. He added that in Korea, "the OG of K-Pop, the King of K-Pop is really G-Dragon."

He continued that the rapper had an amazing interpretation and brought out the original Elvis Presley, the rocker, in him. "Original Elvis the punk interpretation of 'I Can't Help Fall in Love,' I dig it," he stated. He ended his message by saying that he couldn't help but fall in love with GD.

After G-Dragon posted his song cover on YouTube, he quickly trended on Twitter, Naver, Melon and Weibo. AllKpop revealed that over 100 million people viewed the song's topic on China's Weibo after he released the clip, proving he still has it despite his hiatus of four years and holding his last promotion nine years ago.

The Big Bang member also shared the music video on his Instagram and captioned it with "GD + EP + BL = TCB." The first three acronyms seemed to stand for their names, G-Dragon, Elvis Presley and Baz Luhrmann, while TCB might mean Taking Care of Business, which is the name of the music icon's band, per Hypebae.

A couple of weeks before G-Dragon officially dropped his cover of "Can't Help Falling in Love," he shared several hints of his collaboration with Baz Luhrmann. He first shared images of the legendary King of Rock 'n' Roll and the belt that the artist wore himself.

Meanwhile, at a media conference, Baz Luhrmann revealed, via Manila Standard, that he planned to do more projects with K-pop artists in the future, believing American and Korean pop culture was "closely related in history." He said the idols could bring their music to an American classic, adding the K-pop culture started with Elvis Presley in the 1950s.

Elvis Presley's biopic, "Elvis," also features different artists who collaborated on an exclusive soundtrack for the movie. It includes Eminem, Mark Ronson and Doja Cat, while Baz Luhrmann tapped several artists to cover "Can't Help Falling in Love" with their own renditions that he would later release as a compilation playlist this year.
