Heather Mills, Paul McCartney Fighting Like House Pets

Meow! Woof!

According to various sources, the Paul McCartney/Heather Mills divorce is getting uglier and uglier. The former couple is now reportled fighting like "cats and dogs."

The Sunday Mirror says Paul has changed the locks on their London home, frozen their joint bank account and stopped fighting council plans to knock down the lakeside lodge on their estate where Heather is currently living.

But then where will Mills entertain all her gentleman callers?

A source told the newspaper: "It has really got nasty. This is war … Heather and Paul can't stand each other any more and they will fight for everything."

Here's an example of what some may refer to as "absurdly petty:" Heather was allegedly left "speechless" when she received a legal warning after their daughter Bea's nanny took three half-full bottles of cleaning products from their former family home to clearn Heather's new offices.

The warning ordered Mills not to take anything else from the home because the housekeeper was "distressed" by the disappearance of the items.

The source referred to the incident as "astonishing - all over three bottles of cleaning stuff. Heather was absolutely stunned." Of course, McCartney is rather stunned over Mills' gold-digging ways.

Being billed as "the most explosive showbusiness divorce ever," the entire situation has The Gossip downright giddy. And we thought the Jessica Simpson/Nick Lachey break-up was fun fodder!
