Insiders fear the singer will move on to someone else
Jennifer Anistons 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.
Hell spend every waking minute talking to someone and spending time with them and then move on to the next girl, a pal of Johns explains.
And even his ex Jessica Simpson, 27, is worried hell hurt her.
Jessica wants Jen to be aware of what shes letting herself get into with John, a friend tells Hot Stars.
She doesnt 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.
