Shawn Mendes and Camila Cabello are the happiest couple ever! We love that these two are 1) nice, 2) happy, 3) grateful. It doesn't take too much effort just to be nice, people!

The sexy pair show a little PDA by holding hands as they arrive at the Staples Center in Los Angeles, Tuesday night, attending the matchup between the Los Angeles Clippers and the reigning NBA champion Toronto Raptors. Shawn, always the nice guy, thanks our videographer for helping him exit a parking garage earlier in the day.
