The list of BTS fans just keeps growing, even among fellow pop stars.

Just days after American R&B artist Kehlani expressed interest in working with the Kings of K-pop, Charlie Puth touted the boy band (again!) on Twitter.

"I really like BTS's music," the singer-musician tweeted, igniting the Army into an explosion of excitement on the social media site.

In return, the group quoted Puth's tweet and wrote, "We really like Charlie Puth's music."

BTS member Jungkook is a big fan of Puth's as well: Back in January, the Korean singer uploaded a cover of "We Don't Talk Anymore," the American pop star's collaboration with Selena Gomez, to YouTube, prompting Puth to follow BTS on Twitter and express his admiration for Jungkook's rendition on Twitter.

So, could a Puth x BTS or Puth x Jungkook collaboration be in store for the future? Group leader Rap Monster released a collaboration crossover single called "Change" with U.S. rapper Wale this month, so it's not a stretch to imagine more collabs between Western artists and BTS could be on the way.

Anyway, our fingers are crossed!
