On 11 March, Perry hosted Fight On, a free concert for Aussie firefighters and bushfire victims in Bright, Australia, a city located three-and-a-half hours northeast of Melbourne. "Australia has always given me so much love and support," she wrote on Instagram, adding that "FIGHT ON is one way to return that love, and help provide a little bit of joy to a country that's given me so much joy."
For the event, Perry's makeup artist, Michael Anthony, chose to match the singer's makeup to her ensemble, first lining her top lashes with black, then adding a thick stroke of electric yellow that he stacked on top of the black, finishing with a short feline flick at the outer corners of the eyes. To balance out the bold hue, he picked a lipstick in a contrasting shade of rosy pink.
