Washington, Dec 31 (ANI): Heather Mills is afraid that she might have to sell her house to pay the legal bills for her divorce from Sir Paul McCartney.

The animal rights activist has been sued by her former lawyers over 4 million dollars in outstanding bills, and now stands to be forced to put her house on the market to pay off the debt.

"Heather is telling friends that relations have broken down so badly between her and her lawyers she will have to sell her new house to pay the debt," Contactmusic quoted a source, as telling the Sunday Mirror.

"This Christmas she's been facing up to losing her home. It's a shame as she and Bea have just started to settle there," the source added. The former Beatle bought the nine-bedroom home in East Sussex, England, for his estranged wife, and the house is so close to his own property that it gives him easy access to his four-year-old daughter Beatrice.
