Muhammad Ali, 24, flirts with 16-year-old Belinda Boyd at a bakery shop in Chicago, 1966.

Boyd became Ali’s second wife when she was 17-years-old on August 17, 1967. She changed her name to Khalilah Ali. They were married for 10 years and had four children together.

Ali was married four times and had seven daughters and two sons. Ali was introduced to cocktail waitress Sonji Roi by Herbert Muhammad and asked her to marry him after their first date. They were wed approximately one month later on August 14, 1964. They quarrelled over Sonji's refusal to adhere to strict Islamic dress and behavior codes, and her questioning of Elijah Muhammad's teachings. According to Ali, "She wouldn't do what she was supposed to do. She wore lipstick; she went into bars; she dressed in clothes that were revealing and didn't look right." The marriage was childless and they divorced on January 10, 1966. Just before the divorce was finalized, Ali sent Sonji a note: "You traded heaven for hell, baby."

On August 17, 1967, Ali married Belinda Boyd. After the wedding, she, like Ali, converted to Islam. She changed her name to Khalilah Ali, though she was still called Belinda by old friends and family. They had four children: Maryum "May May" (born 1968), twins Jamillah and Rasheda (born 1970; Rasheda married Robert Walsh and has a son Biaggio Ali, born in 1998), and Muhammad Ali Jr. (born 1972). Maryum has a career as an author and rapper.

Ali was a resident of Cherry Hill, New Jersey, in the early 1970s. At age 32 in 1974, Ali began an illicit extramarital relationship with 16-year-old Wanda Bolton (who subsequently changed her name to Aaisha Ali) with whom he fathered another daughter, Khaliah (born 1974). While still married to Belinda, Ali married Aaisha in an Islamic ceremony that was not legally recognized. According to Khaliah, she and her mother lived at Ali's Deer Lake training camp alongside Belinda and her children. In January 1985 Aaisha sued Ali for unpaid palimony. The case was settled when Ali agreed to set up a $200,000 trust fund for Khaliah. In 2001 Khaliah was quoted as saying she believed her father viewed her as "a mistake". He also had another daughter, Miya, from an extramarital relationship. short designer wedding dresses

In 1975, Ali began an affair with Veronica Porché, an actress and model. While Ali was in the Philippines for the "Thrilla in Manila" bout vs. Joe Frazier, Belinda was enraged when she saw Ali on television introducing Veronica to Ferdinand Marcos. She flew out to Manila to confront Ali and scratched his face when they argued. Belinda later said that her marriage to Ali was a "rollercoaster ride—it had its ups and its downs but it was fun". Referring to his infidelities, she said: "Tiger Woods and Arnold Schwarzenegger didn't have nothing on Muhammad Ali". She believed he had "many more" illegitimate children.

By the summer of 1977, his second marriage was over and he had married Porché. At the time of their marriage, they had a baby girl, Hana, and Veronica was pregnant with their second child. Their second daughter, Laila Ali, was born in December 1977. By 1986, Ali and Porché were divorced.

On November 19, 1986, Ali married Yolanda ("Lonnie") Williams. They had been friends since 1964 in Louisville. Together they adopted a son, Asaad Amin, when Amin was five months old.

Kiiursti Mensah-Ali claims to be Ali's biological daughter with Barbara Mensah, with whom he had a 20-year relationship, citing photographs and a paternity test conducted in 1988. She said he accepted responsibility and took care of her, but all contacts with him were cut off after he married his fourth wife Lonnie. Kiiursti claims to have a relationship with his other children. After his death she again made passionate appeals to be allowed to mourn at his funeral.
