Other attendees said they saw them “making out” at the festival, which kicked off its first weekend on Friday, while still others had Perry photobombing them.
A source tells PEOPLE that the pair weren’t shy about showing PDA.
“Katy and Orlando were very cozy together,” says the source. He constantly had his arms around her and at one point she was sitting on his shoulders as she danced and sang.”
Another source added that Bloom, 39, was attentive to his new girlfriend, 31.
“They watched Ellie Goulding and hung out with friends,” the source tells PEOPLE. “They acted super happy. Kept kissing. Orlando made sure Katy had a drink. Even at night, it was very warm. At one point, Orlando fanned Katy to made her more comfortable.”
On Saturday, Perry and Bloom attended Jeremy Scott’s Coachella bash where the singer danced with Mia Moretti in the DJ booth while ex-boyfriend Diplo spun. Other celebrity guests included Perry’s friends Sam Smith, Kristen Stewart and French musician Soko.
The two were first linked at a Golden Globes afterparty in January, and have previously been seen on a weekend getaway to Aspen, Colorado, and at a Los Angeles event earlier this week (even though they walked the red carpet separately).
“They were sitting next to each other,” a source told PEOPLE of the event. “Bloom had his arm sweetly draped around Perry’s chair as they chatted with Allison Williams. The pair seemed to be in a great mood.”
