Mayer continues to fuel Aniston rumours

John Mayer has continued to fuel rumours that he is dating Jennifer Aniston again after a speech he gave to his audience at a recent concert.

Performing at the Hollywood Bowl in Los Angeles on Sunday, the rocker told crowds not to give up on love.

"I believe in second chances! You might have been a pain in the ass the last time around, but you can still start over again from homebase," the Huffington Post reports him as saying.

"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 resembling Aniston was also said to be present and watching in the wings during the performance.

"He [kept] looking, smiling, smirking and winking at her - especially during 'I Don't Trust Myself With Loving You'," a source told E News.

However, her rep later denied that the actress was in attendance, saying: "Jennifer was not at John's concert. It must have been a doppelgänger."
