Cabello explains that the tune, titled "I Know What You Did Last Summer," was written based on events in her own life. "It was something I was going through at the time," the FIfth Harmony singer told Fuse. "Basically, I was talking to this boy — it was literally three days before we wrote the song. My friend had called me and was like, 'Hey, this boy that you're talking to is hitting me up and flirting with me.' I really liked him a lot, so the inspiration was when I found out that he was not involved with just me. I confronted him, and we weren't a thing anymore. That's why I connected with it so much."

The singer previously said that the song was written backstage during a Taylor Swift concert.“We were just backstage. There were like 100 people in my dressing room at the time, and it was madness back there, but I had this guitar and I was just jamming out, and we basically wrote a pre-chorus and a chorus in like 30 minutes,” her singing buddy Mendes said.

As for the two admitting to their romantic relationship, they're still not budging. Cabello also told Fuse that Mendes is one of her "best friends."

"He’s my life coach," she said. "I’m just so irresponsible about things, and he’s always like, ‘Camila, you lost your voice because you’re not drinking enough water! Are you eating good food?’ Whenever I have a crisis, he goes, ‘You need to breathe in and breathe out,’ and gives me a pep talk.”
