Heather Louise McCartney (née See; born December 31, 1962) was born in Tucson, Arizona to Linda McCartney (née Eastman) and Joseph Melville See Jr., an American geologist. She is the adopted daughter of Paul McCartney.

McCartney's parents divorced after 18 months of marriage, because See had left for Africa and expected his wife and daughter to follow. Linda See refused, and sent a letter to her husband stating that she wanted a divorce, which was granted. After raising her daughter on her own in New York City for several years, Linda married Paul McCartney, of The Beatles, in 1969, when Heather was six years old. Also in 1969, Heather was formally adopted by Paul McCartney through legal process (and with prior consent from See, her biological father) and took the McCartney name. Also in 1969, McCartney appeared in the last Beatles movie, Let It Be. She has stated that, although See had a lifelong influence on her, she considers Paul McCartney to be her father.

A half-sister, Mary, was born in 1969, followed by another half-sister, Stella, in 1971 and a half-brother, James, in 1977. Heather has six nephews and two nieces: Mary's four sons Arthur Alistair Donald (born 3 April 1999), Elliot Donald (born 1 August 2002), Sam Aboud (born 11 August 2008) and Sid Aboud (born 3 Sept 2011); and Stella's two sons Miller Alasdhair James Willis (born 25 February 2005) and Beckett Robert Lee Willis (born January 8, 2008), and her two daughters Bailey Linda Olwyn Willis (born 8 December 2006) and Reiley Willis (born 23 November 2010).

Heather Anne Mills (born 12 January 1968) is an English charity campaigner and former model.

Mills came to public attention in 1993, when a collision with a police motorcycle in London resulted in the amputation of her left leg below the knee. She continued to model using a prosthetic limb and sold her story to a tabloid newspaper, using the proceeds to establish the Heather Mills Health Trust, which recycles used prosthetic limbs to amputees unable to afford new ones and campaigns to remove and ban land mines.

She came to further public attention in 2000 when it was announced that she was dating the former Beatle, Sir Paul McCartney. They married in June 2002 and Mills gave birth to Beatrice Milly McCartney on 28 October 2003. The couple separated in 2006 and finalised their highly publicised divorce in 2008.

After her marriage to McCartney, Mills became involved in animal rights advocacy and as of 2012 is a patron of Viva!

She is also vice-president of the Limbless Association and skis in the British disabled ski team's development squad for the 2014 Winter Paralympic Games, winning several Gold medals in the interim.

Larry King (born November 19, 1933) is an American television and radio host whose work has been recognized with awards including two Peabodys and ten Cable ACE Awards. He began as a local Florida journalist and radio interviewer in the 1950s and 1960s and became prominent as an all-night national radio broadcaster starting in 1978. From 1985-2010, he hosted the nightly interview TV program Larry King Live on CNN.

King was born Lawrence Harvey Zeiger in Brooklyn, New York City, to an Austrian immigrant Edward Zeiger, a restaurant owner and defense plant worker, and his wife Jennie Gitlitz, a garment worker, who emigrated from Belarus. King grew up in a religiously observant Jewish home, but in adulthood became an agnostic.

King's father died at 44 of heart disease, and his mother had to go on welfare to support her two sons. His father's death greatly affected King, and he lost interest in school. After graduating from high school, he worked to help support his mother. From an early age, however, he had wanted to go into radio. King is a fan of the Los Angeles Dodgers.
