According to Rolling Stones, Mayer dedicated a song to his girlfriend on the first concert of his Born and Raised World Tour.
He reportedly thanked the Fireworks singer for helping him face the vocal chord problems that have kept him from singing for about 20 months.
“She was so patient,” Mayer said of Perry, who would order food for him when he was unable to speak.
He said she took the time “to continue to get to know me and love me.”
Katy recently shared a pic of herself and Mayer hugging.
