The American Century Celebrity Pro-Am golf tournament is a place where the likes of Justin Timberlake, 'Fresh Prince' actor Alfonso Ribeiro and basketball player Stephen Curry, can all have a dance on a golfing green.
It's also a place where - if you're an unobservant 'Mirrors' singer - you might get slapped in the face by a spectator.
