Camila Cabello and Shawn Mendes are not shy about how much they love each other, and why should they be? Before the pandemic and quarantine, these two never spoke about each other much in interviews, but since they spent all of lockdown together, that's changed. Mendes has been especially open about how his girlfriend's encouragement and support inspired his latest album, Wonder.So it's no shock at all that this happy couple shared their Halloween PDA on Instagram.
