Peter was said to have made the move first. But when the glamour girl found out she reportedly wanted to beat the 'Mysterious Girl' hitmaker to court and allegedly called her team of attorneys to take action as well.
"It's quite sad really and nothing more than a petty snipe from Ms Price," the Sun quoted a family lawyer as saying. "It's her way of saying, 'I am not allowing you to divorce me - instead I am going to divorce you.' It's just a way of sticking your fingers up at your ex through legal process. It's about emotion - nothing else," the lawyer added.
A pal of Peter said: "Peter isn't really asking for any money or property from Katie, but there are a few pieces of furniture that he wants back. What he wants most is his gym equipment. The financial agreement is almost there, but they've still got to thrash out custody issues."
