The original inspiration for the lyrics came about when Puth was driving on Santa Monica Boulevard
with his friend, whom he hadn't seen in four months. He recalled:
"Last time I saw him he was so infatuated and in love with this girl, and would literally talk about
her every second, and always just literally with the ups and downs and the sideways and whatever."
"When I saw him after four months of not seeing him, of being on tour, I was like, Oh, how
is so and so doing? And he was like, Oh, we don't talk anymore. And literally as he said
that I was like, 'We don't talk anymore. We don't talk anymore. We don't talk anymore.
Like we used to do.' Simple."
• Charlie Puth wrote the song in Tokyo, Japan. He said
"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."
• The song features
. He said:
"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. 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."
"I'm good friends with her now, and we talked about wanting to collaborate, and I was finishing the song,
and I was like, 'Wouldn't it be cool if you sang the second verse?' And that's really how it
happened. She came over; she recorded it. I didn't even have a studio set up; she recorded it in my closet,
and it really added a lot to the record."
