Peter Andre has declared war on estranged wife Katie Price.

The 'Mysterious Girl' singer is said to be furious with the "vicious slurs" the glamour model has been making against him and has called an urgent meeting with advisers and friends to decide his next move.

A source said: "He is fuming about what's been said. He's going to meet his people to see what can be done. As far as he's concerned, it's a new low, getting pals to take sides and make vicious slurs."

Katie - also known as Jordan - has blamed the break-up of their three-year marriage on Peter and now her friends are starting to publicly attack him.

Former Liberty X singer Michelle Heaton - who was Katie's bridesmaid at their 2005 wedding - defended her pal, saying she had been unfairly treated by the media.

She said: "It makes me furious when I see the stick Kate is getting. She is made out to be the baddie.

"The simple fact is that he left Kate. She is a strong woman though and she refuses to play the victim."

Peter - who raises three children with Katie, Harvey, seven, Junior, four, and two-year-old Princess Tiaamii - wants to defend himself but doesn't want to behave in the way Katie has.

A source said: "Kate can do what she wants. Peter won't get involved in tit-for-tat accusations. He knows how it looks to the public. He's happy for Kate to continue self-destructing."
