Stella McCartney, daughter of Paul McCartney and his first wife Linda, has no kind words for her estranged stepmother, a London tabloid reports.

The News of the World reported that Stella called Heather Mills-McCartney an epithet usually used for female dogs when told that her stepmother had claimed that her father hit the late Linda McCartney.

"Why did you marry her? She's been a manipulative cow from day one," she reportedly screamed at her father. "The cow won't be happy until she destroys all of us and our memories of our mother."

The News of the World, one of London's most notorious tabloids, said that Stella called her stepmother "a money-grubbing b--." The pregnant fashion designer is also reported to have said she did not want to have a child if Mills-McCartney would be its grandmother.

McCartney's "Ecce Cor Meum" or "Behold My Heart," a classical work, premieres in London soon. The work is dedicated to Linda McCartney, who died of breast cancer in 1998.
