LATEST: Sir Paul McCartney's daughter STELLA reportedly launched a foul-mouthed tirade aimed at Heather Mills when she discovered her stepmother had accused her father of domestic violence in leaked court papers. Pregnant Stella made the extraordinary comments after Mills claimed the former beatle hit his first wife - the fashion designer's mother Linda Mccartney. According to British newspaper the News Of The World, Stella told her dad, "I'm going to kill that b**ch. I can't believe what she's doing. I'm going to kill her. "I told you she was a b**ch. Why did you marry her? She's been a manipulative cow from day one. The cow won't be happy until she destroys all of us, and our memories of our mother."
