-Shawn Mendes, the singer of top 5 hit Stiches and opening act for Taylor Swift's 1989 tour, and Camila Cabello of Fifth Harmony, wrote and sung a duet together called I Know What You Did Last Summer
-The duet has been suspected/announced ever since Shawn and Camila started hanging together months ago, but a preview came out today
-There's a website coming soon for the song http://www.ikwydls.com/
-Camila said that Shawn just grabbed a guitar and wrote the song with her backstage or something
-Camila and Shawn have been favoriting tweets about fans supporting them doing any projects they want
-5H fans are freaking out and think this is a sign the Camila is going solo or that Shawn should have done a duet with the whole band
-Some 5H fans support Camila and think there's a double standard with her because people supported Dinah becoming a Disney princess, Normani's dance video, and a 1 second clip of Ally in a PTX video
