John Mayer dedicates song to Katy Perry

Singer-songwriter John Mayer dedicated his new song "A face to call home" to on-and-off girlfriend, singer Katy Perry at the opening night of his "Born & Raised" tour in Milwaukee, Wisconsin.

The 35-year-old publicly declared his love for Perry, who was present at the concert July 6.

"I was just getting to know a girl and started really reconsidering just how difficult everything was going to be, right as he (the doctor) was putting the needle through my neck, because I was just getting to know this girl, and I wasn't going to be able to talk to her," contactmusic.com quoted Mayer as saying.

"And she was more incredible than I ever thought because I would whisper in her ear and she would order for me with the waiter, and I would whisper in her ear and she would tell people, 'It was nice to meet you, he says.' We did a lot of whispering," he added.

He also shared that the couple spent a lot of time chatting online via video when they were apart and that he is grateful to Perry for making so much effort when he could barely speak.

"She was so patient as to even continue to get to know me and love me, while we would be on speaker phone," he said.

Mayer then dedicated his new song to Perry. "This is a long time coming for us and I want to dedicate this next song to Katy, my Katy."

The couple got back together last month shortly after Perry admitted in an interview that she was still "madly in love" with Mayer.
