UPDATE 2: The first quote mentioned in the original post was not initially attributed as it should have been. The quote came from the Express, via Ryan Seacrest's radio show. Seacrest first mentioned the story on his show Thursday morning and then HuffPost found the quote on the Express website.
Let's break it down: I don't think I ever said "I believe in second chances!" but I can't be 100 percent sure, as it's possible I could have accidentally said something succinctly and to the point. The next sentence is from the song "Half of My Heart," in reference to the idea that meeting new people allows for hiding old mistakes. (Well, for most people at least.) The sentence about texting comes from the show's encore, "Edge of Desire," in a moment of giving people permission not to beat themselves down for still wanting someone. Two sentences about different things at different points in a concert.
He does not deny that he and Aniston are dating.
PREVIOUSLY: Are John Mayer and Jennifer Aniston back on? Mayer seemed to indicate they might be when he spoke in front of a crowd of 18,000 at his concert on Sunday at the Hollywood Bowl in LA.
"I believe in second chances!" he said, reports the Express. "You might have been a pain in the ass the last time around, but you can still start over again from home base. Next time you get a text from the one you love just text back 'come over' - no matter what happened in the past. If you really love someone, just tell them and be with them."
A woman who resembled Aniston was rumored to be in the wings while Mayer performed, though her rep has not verified she was there.
"He keeps looking, smiling, smirking and winking at her--especially during 'I Don't Trust Myself With Loving You,'" someone emailed E! News during the show.
Aniston and Mayer split for the second time in March 2009.
