Perry also said that she might collaborate with Cyrus in the future.
"I don't know...maybe...she's got an incredible voice," Perry told eonline.com at the iHeart Radio Music Festival here.
The 28-year-old also said that she was excited about Cyrus's new song "Wrecking ball" before it was released and she knew it would be a hit.
"I have heard her sing 'Wrecking ball' before that single came out and I tweeted about it a long time ago before it even came out and I was just so excited about it for her. She's got a set of pipes that are incredible," she added.
