"Look in my eyes, they will tell you the truth/ The girl in my story has always been you/ I'd go down with the Titanic, it's true, for you, lover," Mendes later continues, seemingly in a nod to he and Cabello's long friendship that preceded things like making out at the beach and making out on Instagram , and making out at a basketball game . I'd also guess that the couple's go-to movie about love — albeit disastrous — is James Cameron's Titanic.
