It seems John Mayer and Katy Perry are on again after all. The singer/songwriter made a major romantic gesture during his Milwaukee show on Saturday when he dedicated a love song to the pop star.

Mayer, 35, gushed over Perry, 28, recalling how "patient" she was following his voice surgery.

"I was just getting to know this girl. ...She was more incredible than I ever thought. ...She would order for me ...and she would tell people, 'It's nice to meet you, he says,'" he told the audience. "When I was in Montana and I wasn't speaking with really bad phone service ...she was so patient as to even continue to get to know me and love me."

Following this sweet proclamation, Mayer dedicated his love song "A Face To Call Home" to Perry, saying, "I wanna dedicate this next song to my Katy, who is my face to call home."
