The newly engaged couple couldn't keep their hands off each other at the Indio, California, music festival, as they were photographed sharing a passionate kiss while wandering around the event.
Bloom sported a bright yellow hoodie and matching shorts for the occasion, while Perry's flame-patterned pants were easily spotted from the crowd. She paired the statement piece with a patent leather jacket, matching black top and black baseball cap.
Among the pair's list of artists to check out on Friday was Childish Gambino. Perry, 34, and Bloom, 42, were seen rushing over to the Coachella stage to catch his set.
"Both have been married before and know what they want to do different this time," the source said of Perry's ex, Russell Brand, and Bloom's former wife, Miranda Kerr.
"Katy and Orlando love to have fun together, in life and with their friends, and that’s what they are planning for their big day," the source explained. "The couple is serious about their future, but they aren’t stressing about hammering everything out now. Katy and Orlando are both very busy, and when things slow down they will get married, but right now there is no set date."
