Are John Mayer and Katy Perry back together? Well, nothing's for certain, but all indications point to a possible reconciliation between the two.

On Saturday, John Mayer took the stage again, a year after his throat surgery last summer. Kicking off his "Born and Raised Tour" in Milwaukee, it was an emotional night for the singer who's been through a lot the past year. But what made the concert a true standout was when the "Half of My Heart" singer dedicated a special song to Perry.

He remembered how the "Wide Awake" songstress stood by his side during his rough time with surgery, literally being his voice while he was forced to undergo a 10-month vocal rest.

"[Katy is] more incredible than I ever thought," Mayer said, adding how "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," E! Online noted.

The soliloquy almost seemed to set the mood for Mayer's final song of the night, which he proudly dedicated to Perry.

"To Katy, who is my face to call home," followed by his romantic ballad "A Face to Call Home."

Fanning more rumors, Katy Perry also posted an image of her and Mayer spending the Fourth of July together.

But the news doesn't seem to be a surprise anymore as Perry has always been vocal about her feelings for Mayer.

In an interview with Vogue, Perry said, "I still am madly in love with him. All I can say about that relationship is that he's got a beautiful mind....Beautiful mind, tortured soul. I do have to figure out why I am attracted to these broken birds."
