Olivia Rodrigo may have taken her final bow on the 'GUTS' world tour stage in Manchester last month, but the pop phenom isn't letting the confetti settle just yet. The 22-year-old singer has announced a 'GUTS' World Tour Book - a lavish, 136-page hardcover time capsule that captures the whirlwind energy of her first-ever headlining arena trek. Rodrigo's 'GUTS' tour was a globe-spanning, 97-show odyssey across North America, Asia, Australia, Europe and South America.
