To celebrate ending her successful "Witness" tour in 2018, Perry got an intricate fine-line Saturn design tattooed on her right wrist. The beautiful tattoo was drawn by the widely known celebrity tattooist Dr. Woo. The hitmaker shared the inspiration behind the piece on her Instagram, writing, "The planet in the middle is Saturn as this journey has taught me many lessons with a few tears along the way BUT I am happy to report a sense of real resilience as we wrap. I share this insignia with 45 other tour mates and moreover an incredible year of memories with over 100 beautiful & kind humans and a numerous amount of gracious attendees."
