Heather Mills apparently doesn’t just look like a terrier, she acts like one too.

Mucca has hired a team of accountants to prove that her blessedly-soon-to-be ex-husband Paul McCartney is worth more than he said he was, in an effort to get more blood from that poor stone.

Miss Mills has told friends she cannot look after Beatrice on £35,000 a year, the sum awarded at the High Court.

One said: “Heather says she can prove the amount of money that is being given to look after Bea will not last over the year. She is putting it to the test.

“Even with Bea travelling in economy Heather says it’s not enough. She is keeping every receipt — including her invoice to her security team — to show that £35,000 is just not sufficient.

“Heather’s thinking is that Bea should not be seen to have a different lifestyle when she is with Heather compared to Paul — and she is going about proving that is not possible.”

God forbid she should use any of the MILLIONS OF DOLLARS he gave her to support her own daughter. Or, you know, try to get a job. Preferably something in waste management.
