According to RadarOnline, friends think the recently divorced Katy should break it off with John before he breaks her heart.

The source revealed:

"Katy’s friends and family haven’t taken to John at all, in fact they are worried that she is headed for heartbreak. She’s been telling everybody who cares to listen how great John is and it’s clear that she is totally in love with him. At first, she was quite careful with John and said she wasn’t ready for a relationship and just wanted to have fun. But now she appears to have fallen dangerously in love with him and her friends are concerned. Despite the fiery image Katy likes to present, she’s actually more fragile than that, and when John dumped her a few weeks after they first got together she was devastated. Now that she has invested more feelings in John and has let her guard down, there’s only one way this can end… in disaster!”

The source goes on to say that John has been after Katy for a long time, and made her believe he really wants to change his ladies' man ways, even though they think he is just lying.

Hopefully, this is all speculation - Katy is too good of a girl to get her heart broken again!
