Keough married Presley at the Church of Scientology in Hollywood on October 3, 1988. Keough is a Scientologist, and met Lisa at the Scientology Celebrity Centre. The couple had dated for three years before marriage. Keough and Presley spent a three-month honeymoon on a cruise in the Caribbean, on a yacht owned by Church of Scientology, the SMV Freewinds. Scientology publicists stated that they were accompanied on the ship by Scientology celebrities including musician Chick Corea, and Olympic gymnast Charles Lakes. Priscilla Presley released a statement through publicist Paul Bloch: "Lisa and Danny have been talking for the past year about getting married and starting a family ... I couldn't be happier for the two of them at this very special time in their lives."
Presley announced she was ending her marriage to Keough in April 1994, and the couple divorced on May 3, 1994, in the Dominican Republic. At the time of the divorce, Presley stated "Danny and I will always love each other. However, friendship was more suitable for us than marriage. We have two wonderful children and we plan to have joint custody of them." In 1994, Keough said he would seek custody of his children with Presley, due to child molestation charges against Michael Jackson, who Presley married after their divorce.
Keough is a bass guitar player in Presley's band, and also serves as her musical mentor. Lisa Marie Presley still regards Keough as a close friend. Keough lives in the guest house on Presley's property. Presley described her relationship with Keough after they separated: "I don't know how, but we've managed to stay close ... There's others that I have pain or betrayal associated with that I won't have anything to do with. But he and I had a special thing. Unconditional." In a 2003 interview with The Commercial Appeal, Presley commented on reports that she and Keough were planning to remarry: "Danny is my best friend, always has been, always will be. I love him unconditionally, but we are not together. It's not like that." Keough and Presley became closer after Presley divorced Michael Jackson. Keough's younger brother Thomas Keough had been an official witness at Presley's marriage to Michael Jackson.
