Sir Paul McCartney's estranged wife Heather Mills saw her recent 40th birthday party ruined after her house flooded. The former glamour model - who is currently locked in a bitter divorce battle with the Beatles legend - invited dozens of guests to the celebration which were held in a marquee at her East Sussex, England, mansion on Saturday (12Jan08). But Mills' guests were shocked to find the house draped in tarpaulin after heavy rain had caused the roof to leak, flooding the top floors of the property. A source tells British newspaper the Daily Mirror, "It was distressing for Heather - her bedroom was soaked." Mills is planning on moving back to her former home in Brighton, England, after selling the nine-bedroom East Sussex property in a bid to pay her spiralling legal bills.
