Washington, Jan 14 (ANI): Sir Paul McCartney's estranged wife Heather Mills' 40th birthday bash was ruined when her house was flooded after heavy rains, leaving the guests shocked.

The former model had invited many guests to celebrate her birthday in a marquee at her East Sussex, England, mansion.

However, guests were taken aback when they saw the house being deluged by heavy rains. It caused the ceiling to leak and the top floors of the property were soaked in water.

"It was distressing for Heather - her bedroom was soaked," Contactmusic quoted a source, telling British newspaper the Daily Mirror,

Mills is now heading to her former home in Brighton, England, after selling the nine-bedroom East Sussex property in order to pay her escalating legal bills.

Currently she is entangled in a bitter divorce battle with the former Beatle star. (ANI)
