Selena Gomez and Charlie Puth's 'We Don't Talk Anymore' Is More Personal Than You Think

Puth breaks down their new song and why Selena can really "relate" to the track.

Charlie Puth knows how to pull off the perfect duet. Between his Golden Globe-nominated song "See You Again" with rapper Wiz Khalifa and "Marvin Gaye," his feel-good collab with Meghan Trainor, his smooth vocals are the perfect addition to any song. But his latest single might just be our favorite collaboration yet.

On Thursday, the 24-year-old singer-songwriter teased a new song with (queen) Selena Gomez titled "We Don't Talk Anymore" -- and better yet, the duo accompanied the catchy snippet of the hot track with an adorable video. Everything from the beat, to Puth's sunny smile is the definition of fire.

But the song's origins couldn't be any more serendipitous. It all started with a simple guitar riff and a phone conversation with a newly single friend.

"I wrote ['We Don't Talk Anymore'] in Japan," Puth told MTV News over the phone from his hotel in New York City. "I was in my hotel room, at the Mandarin Hotel, looking out at this wonderful city from the top floor, and I called my guitarist who was in the next room and I said, 'Dude, can you come to my room really quickly and play this guitar line?' I didn't have a microphone, so I recorded his guitar with my iPhone, and I put it in the mix. Then, we went to the Philippines the next day, and I put the kick drum in."

"I remember a conversation I had had with my friend," he added. "He had just broken up with this girl, and I was like, 'So, are you going to talk to her anymore?' And he was like, 'Nah, we don't talk anymore.' I was trying to cheer him up, so I did a dumb little face, and I was like, [singing] 'We don't talk anymore.' I was just trying to cheer him up, but it became a cool melody, and I realized that this guitar beat fit perfectly over it."

Puth originally played the song for Gomez thinking that she'd not only appreciate the cheery beat but also the song's timely subject matter.

"I met up with Selena, and she went through a very public relationship, on and off, and she could just relate to the song and the lyrical sentiment," Puth said. "I was playing the song for her, and she just started singing the second verse. I got chills. I was like, 'Oh my gosh, that sounds so real. You need to sing on it.' And she said yes."

As for the impromptu dance party, well, that was all Sel's idea. "I met up with her [Wednesday night] and she started a mini dance party in my tour bus with the song. She's really amazing."
