Supermodel Kate Moss has branded the estranged wife of Sir Paul McCartney Heather Mills a liar.

In leaked divorce documents, Mills claims that she was forced to crawl on her hands and knees to the toilet at night after her husband refused to allow her to use a bedpan in their bedroom.

However, Moss a friend of Macca�s daughter Stella has claimed that statements in the leaked divorce papers are �utter bullshit�, reports the Sun.

A friend of Moss� told the tabloid: �Kate reassured Stella that she knew Heather was a liar because she had seen her hopping around.

�She said she was �jumping around like a fucking gazelle� and is prepared to swear to it, in a court if necessary.�

The friend went on to say that Moss knew Heather was �extremely athletic� and �not the sort of person to crawl anywhere.�

She added: �Kate has met Heather and has seen her with her prosthetic leg on and off. She�s now been telling everyone what a scheming liar Heather is.�

Oh dear�if I were Ms Moss I would stay well out of this battle.
