Sir Paul McCartney has reportedly frozen the joint account he shares with estranged wife Heather Mills.

Mills was withdrawing "obscene amounts" of money, according to sources, leaving McCartney unimpressed.

A source said: “Sir Paul was disgusted by the obscene amounts of money Heather was withdrawing. It seems she is determined to spend money while she has the chance before the divorce goes through.”

McCartney has also had to change the locks on the house they shared in London.
