Kate Moss has reportedly told friend Stella McCartney that she is prepared to go to court to give evidence against Heather Mills in the divorce case between Heather and Stella’s dad, Paul McCartney.

According to papers leaked last week, Heather claims various types of abuse she suffered from Paul including how she had to crawl to the bathroom at night because Paul refused to let her use a bedpan in the bedroom.

A source claiming to be a friend of Kate’s told the Sun: “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 f****** gazelle’ and is prepared to swear to it, in court if necessary.”

“Kate has met Heather and has seen her with the prosthetic limb on and off. She’s now been telling everyone what a scheming liar Heather is.”

Kate is said to have added that she considers Heather “extremely athletic” and “not the sort of person to crawl anywhere”.
