John Mayer Blathers on About Katy Perry During Concert [VIDEO]

Could John Mayer be changing his tune about actually saying nice things about women he dates? The answer may be yes.

During his concert stop in Milwaukee this past weekend, John stops singing and tells the crowd a story about "This Girl" he was dating and just getting to know when he was having his throat issues.

The rumor mill is going into overdrive that the two of them are back together, and it seems the second time around may be even better for them. John Mayer has a reputation of being a heart breaker and blabbing about it, but so far so good for Katy.
