Uh oh, Peter Andre may want to watch his back as his ex-wife Katie Price, is on the war path...

Katie is threatening to 'expose' Pete (whatever that means) in a new tell-all book about her life and has told the singer to be 'scared'.

The galmour model attended the Oscars parties in LA (we have no idea why) and told the Sunday Mirror: “I don't want him to be unhappy but people need to realise he's not what the public think he is.

“I want him to move on like I have, but he won't.

“You just wait. It's time the truth came out on me and Pete.”

She added: “I'm not going to hold anything back. I'd be very scared if I was him.”

We wonder what Katie has to tell? After Pete's fling with a blonde model was discovered last week, we wonder if he has any other skeleton's in his closet?

Katie and Peter in happier times...
