Katie Price has banned Peter Andre's name from her house.
The glamour model has reportedly vowed to "destroy" her estranged husband after he walked out on her in May.
She has already had an X drawn over the tattoo of his name on her wrist, and is also rumoured to be planning a sixth breast operation.
A friend close to Katie, 31, told Britain's Daily Star newspaper: "All she cares about is making sure she stays more famous than Pete. She sees her surgery plans as a big two fingers up to Pete. She'll do anything to annoy him.
"She won't even allow the name 'Pete' to be said while she's in the room.
"She is out of control and flies into rages. She rants about how she's going to 'destroy' Pete and how she'll use ever power at her disposal to 'ruin' him. She's like a woman possessed."
Meanwhile, Peter has banned Katie - also known as Jordan - from a birthday party this weekend for their youngest daughter, Princess Tiaamii, who was two on Monday (29.06.09).
He has also vowed to have his own tattoo of Katie's name removed from his ring finger.
Writing in his magazine column, he said: "'I married Katie Price, not Jordan, but Katie Price left the building a long time ago. Nothing she can do can hurt me anymore and nothing she does surprises me.
"In terms of my 'Kate' tattoo, I'm sure I'll have it removed at some point."
