Lmao at anyone trying to talk **** about her for this.
It's not like she travels to Germany every day or on her free time so spending time with her fans who she hardly sees is more important than being late, even if it seems unprofessional because it's her fans that buy her products and material not the press.
Unprofessional is blazing it up backstage, getting high as **** and being late while thousands of fans are waiting for you to perform.
