In the past, Rihanna has maintained a few unconventional pre-show rituals.

Initially, things follow a typical routine: “I eat lozenges, steam my voice, do my makeup. I Skype my vocal coach, and we sit there at the makeup table and do warm-ups for about a half hour,” she disclosed to Esquire in 2011.

However, she then adds some fun elements: “My personal assistant, who also serves as my bartender, brings me a diluted shot to ease the harshness, typically with orange juice or soda water and lime,” she explained. “It’s a must-have for me. I take it quite seriously, so there’s always a level of anxiety. I tend to overanalyze everything related to my job. The drink helps calm my nerves. I sip it while observing the opening act from my dressing room. Occasionally, I venture into the audience, donning a large hoodie to blend in.”
