Heather Anne Mills is an English former model, businesswoman and animal rights activist.
Mills came to public attention in 1993 when she was a model and was run over by a police motorcycle in London. The accident resulted in the amputation of her left leg below the knee, but she continued to model using a prosthetic limb and later sold her story to the tabloid journal News of the World.
She began a relationship with Paul McCartney in 2000. They married in June 2002 and Mills gave birth to Beatrice Milly McCartney on 28 October 2003. They separated in 2006, and finalised their divorce in 2008.
After her marriage to McCartney, Mills became involved in animal rights advocacy and as of 2024 is a patron of Viva! and Viva! Health. She is also vice-president of the Limbless Association.
