This is far more serious than the long divorce battle she's facing with former husband Paul McCartney. Heather Mills is said to undergo surgery after a metal plate in her pelvis broke.

Britain's Mirror newspaper reported Thursday October 18th that Mills, who lost a leg when hit by a police motorbike back in 1993, is in "absolute agony" after a metal plate in her pelvis broke. "It separated after a screw came out. Two weeks ago, the joint moved and is out of line, it's not stable. She could face a serious operation," a friend of Mills revealed.

The surgery reportedly could take Mills up to six months to recovery, the friend added.

In August 1993 Mills was hit by a police motorcycle while crossing the road near London's Kensington Palace, which resulted in crushed ribs and a punctured lung. She needed a metal plate put into her pelvis and also the amputation of her left leg below the knee, but is having a prosthetic leg since then.
