What is it about a young Hollywood couple in love that makes fans gush over them? Is it the exchanged glances, the loving embraces, or the love duets they sing? Probably all the above. Shawn Mendes and Camila Cabello are Hollywood's new "it" couple on the block. The two singers spend every waking moment together, whether that's on stage, in music videos, on red-carpet events or at basketball games, it doesn't matter. Love is in the air for these two.
