I think ive told this story once but last year she stopped at 3am when she landed at the private airport in Melbourne and took photos with me and 3 of my friends.. true queen
She is always replying, RT'd, DM'ing, faving things on twitter.
After her UK shows (it might be elsewhere as well) she ALWAYS stopped after the show so fans could get pictures (for free) and she would always upload them on Instagram.
She also got at least 2 fans up every night to perform Whip It with her on this tour. So 100% Nicki.
