Insiders fear the singer will move on to someone else

Jennifer Aniston’s new relationship with John Mayer will leave her heartbroken, say insiders.

The couple have been inseparable over the last few weeks but it is feared the relationship won’t last.

‘He’ll spend every waking minute talking to someone and spending time with them and then move on to the next girl,’ a pal of John’s explains.

And even his ex Jessica Simpson, 27, is worried he’ll hurt her.

‘Jessica wants Jen to be aware of what she’s letting herself get into with John,’ a friend tells Hot Stars.

‘She doesn’t want her to make the same mistakes. John is a ladies’ man.’

Last week Jen was spotted kissing the musician backstage at his concert in Orlando.

John, 30, split with Jessica last summer.
