FUSE TV - Camila Cabello Interview: Fifth Harmony’s Next Album & Why Shawn Mendes is her "Life Coach"

As Fifth Harmony prepares its second album from a probable 2016 release, one of the girl group’s members, Camila Cabello, has taken a quick solo detour to help out her pal Shawn Mendes with a duet. “I Know What You Did Last Summer,” their joint single from Mendes' Handwritten Revisited reissue, was released earlier this week, and Cabello tells Fuse that the experience of unveiling the duet with the Canadian singer-songwriter was a moving one for her.

“This song meant a lot to me … it was almost like getting to explore the acoustic-storyteller part of me,” says the 18-year-old singer. “When it came out at midnight [on Wednesday], I received texts from all my friends who knew I was working on it, who I sent GarageBand recordings of me writing my own songs, and them just being like, ‘I’m so proud of you.’ I had a good 10-minute cry. I was FaceTiming with Shawn at the time, and my mom in a room. I was like, ‘I’m so emotional right now!’”
