Katy, 34, dropped the big news on the red carpet at the iHeartRadio Music Awards.
She was asked if the rumors about her and the "End Game" singer collaborating were true. "I mean, I'm making music with Zedd, so I'm open," she smirked.
Her "365" collaborator then chimed in. "I programmed her to make music with anybody, it's great," he said.
The pop stars have had a big reputation for feuding with another, allegedly over backup dancers, but all that ended when the "California Girls" singer extended an actual olive branch when Taylor's Reputation tour kicked off in May 2018. She sent her a note that read, "Hey old friend, I've been doing some reflecting on past miscommunications and the feelings between us, I really want to clear the air."
The 29-year-old shared the gesture on Instagram. "So, I just got back to my dressing room and found this actual olive branch. This means so much to me," she said.
