Santiago, Chile - Olivia Rodrigo turned up the heat as she transformed her GUTS World Tour set for her lengthy run of music festival gigs.

The 22-year-old made her headlining debut at Lollapalooza Chile on Friday – the first of an extensive run of festival appearances that will comprise the GUTS World Tour (Spilled) leg.

Olivia traded her signature purple hue for a dark red vibe in the show's new visuals, opening the performance with a fiery clip that saw her stand in a ring of flames as he wrote "GUTS" out in red lipstick.

She kept the color theme going with a bright red bodysuit paired with black boots that she wore throughout the 90-minute performance.
