Michael Douglas’ Ex-Wife Ties the Knot With a Member of Princess Diana’s Family

Diandra Luker Douglas, the former wife of Hollywood icon Michael Douglas, has entered a new chapter in her life by marrying William Legge, the Earl of Dartmouth. Their union ties her to British nobility and, through her husband, to Princess Diana’s family—25 years after her high-profile divorce from Michael Douglas.

The wedding took place quietly in Gibraltar, coinciding with the Earl’s birthday. The intimate ceremony, attended by only a handful of witnesses, marked Diandra’s official transition into the title of Countess of Dartmouth.

William Legge’s mother, Raine Spencer, was married to Diana’s father, John Spencer, the 8th Earl Spencer, making William and Diana step-siblings. Through this marriage, Diandra has become linked to one of Britain’s most storied aristocratic families.

Before this new chapter, Diandra spent 23 years married to Michael Douglas, with whom she shares one son, Cameron Douglas. After their divorce, she maintained a low profile while pursuing a creative career as a film producer and documentarian.

Her filmography includes Off the Menu: The Last Days of Chasen’s (1997), Broken Lines (2008), and work on PBS’s American Masters series—projects reflecting her artistic vision and independence beyond the Hollywood spotlight.

William Legge, meanwhile, brings a background in finance and politics. An Oxford and Harvard graduate, he has served as a Member of the European Parliament, an executive in business, and a fellow of the Institute of Chartered Accountants.

Together, the Countess and the Earl of Dartmouth symbolize a union of art and politics—a blend of Hollywood glamour and British tradition that underscores Diandra’s enduring ability to reinvent herself with grace.
