Jen Aniston warns Katy Perry to 'watch her back' with Hollywood bad boy John Mayer
‘Jen will never get past what John did to her,’ says a source.
‘When they dated she really thought he was “the one”, but it was horrific when he dumped her
by text message.
‘Having seen how serious they’re getting, Jennifer told Katy not to believe his “pretty words”.
‘She’s also urged Katy not to believe – or accept – any proposal unless she’s absolutely sure he’s changed.’
Jen, 44 – now engaged to Justin Theroux, 41 – dated notorious love rat John for 11 months before their acrimonious split in March 2009.
She’s stressed to friends that she’s far from jealous, saying she doesn’t want to see the former Mrs Russell Brand get hurt again.
