Music good guy - turned bad guy - turned country guy John Mayer kicked off his Born & Raised Tour Saturday July 6th in Milwaukee with a MAJOR PROFESSION of LOVE for pop singer Katy Perry.

In front of a HUGE crowd John dedicated his song “A Face to Call Home” to his on-again off-again girlfriend Katy. He confided about his throat surgery, "She would order for me...and she would tell people, 'it's nice to meet you, he says'...When I was in Montana...with bad service... she was so patient as to continue to get to know me and love me."

Of course Katy was in the audience and witnessed the whole thing!
