Diandra Luker is a film producer, Michael Douglas’s first wife, and the mother of actor Cameron Douglas. She married Michael in 1977. Their divorce became final in 2000. She later raised four children, built film credits of her own, kept close ties to Mallorca, and married William Legge, the 10th Earl of Dartmouth, in 2025.
Here’s what to know about Diandra Luker, from her early life and marriage to Michael Douglas to her family, film work, Mallorca ties, and life today.
Who Is Diandra Luker?
Diandra Luker first became famous through her marriage to Michael Douglas.
She was not an actress. Her own work took place behind the camera.
She later became a producer and raised a family that grew beyond Cameron.
Mallorca also stayed important in her life for many years.
In 2025, she entered another public chapter when she married William Legge, the 10th Earl of Dartmouth.
Her Early Life and the Road to Michael Douglas
Mallorca was part of Diandra’s life from a young age.
In a 2011 Harper’s Bazaar interview, she spoke about growing up in a small town on the island.
She later attended schools abroad and studied in the United States.
During the events around Jimmy Carter’s 1977 inauguration, she met Michael Douglas in Washington.
Michael was already known as an actor and producer. Diandra was still a student.
The relationship moved fast.
A Washington Post report from March 1977 said they met during the inauguration period and married soon after.
The 1977 Wedding and Cameron Douglas
Michael Douglas and Diandra married on March 20, 1977.
The wedding took place at the Beverly Hills home of Michael’s father, Kirk Douglas.
The Washington Post named Gregory Peck, Warren Beatty, Jack Nicholson, and Karl Malden among the guests.
The marriage brought Diandra into one of Hollywood’s best-known families.
Michael’s career was also growing fast. That meant more press, public events, and attention around their home life.
The couple welcomed Cameron Douglas in December 1978.
Cameron later became an actor. His adult life also included addiction, prison, recovery, writing, and fatherhood.
Diandra stayed closely involved in his life through those hard years.
Her Work as a Film Producer
Diandra Luker built her own credits behind the camera.
She served as an executive producer on Off the Menu: The Last Days of Chasen’s.
The film looked at the closing of Chasen’s, the famous Los Angeles restaurant.
Reviews in the Los Angeles Times and Washington Post credited her as an executive producer.
She later worked on Broken Lines, a 2008 drama with Paul Bettany and Olivia Williams.
The British Council’s UK Films database lists her among the film’s producers.
These projects give her a clear career outside her marriage.
Mallorca and the S’Estaca Estate
Diandra’s old link to Mallorca later became part of her life with Michael.
The couple bought S’Estaca, an estate near Valldemossa, around 1990.
The property became one of the best-known homes tied to Michael Douglas.
For Diandra, the island had a deeper meaning. She had known Mallorca long before the purchase.
After the marriage ended, both former spouses still used the estate for years.
Michael later bought her share. That ended their shared ownership.
Diandra’s own link to Mallorca continued.
Separation, Divorce, and Life After the Marriage
Michael and Diandra separated in 1995.
The divorce became final in 2000.
That is why both years appear in stories about the end of the marriage.
1995 marks the separation. The legal marriage ended in 2000.
Michael married Catherine Zeta-Jones later that year.
Many celebrity pages focus on the money tied to the divorce.
But family remained the longer link. Michael and Diandra still shared a son. They also had the Mallorca estate to deal with after the split.
Diandra kept a lower public profile after the divorce. She still appeared at events, but she did not make celebrity coverage the center of her life.
Her Family Grew Beyond Cameron
Diandra later became the mother of three more children.
She had twin sons, Hudson and Hawk, through a surrogate while she was with Zach Bacon III.
She later adopted a daughter, Imara.
Harper’s Bazaar documented the family in its 2011 profile.
The article described Diandra at home with the twins and Imara.
Years later, she spoke in a Mallorca interview about taking the younger children to visit Cameron during his time in prison.
She wanted the siblings to know one another even while Cameron was away.
This part of her life shows why the years after Michael Douglas were about much more than divorce.
She Married William Legge in 2025
A major update came in September 2025.
Diandra Luker married William Legge, the 10th Earl of Dartmouth, in Gibraltar.
Bride Gibraltar, which arranged the wedding, states that the ceremony took place on September 17, 2025.
The event was held at The Dell in Alameda Gardens.
It was a small private wedding.
William is the son of Gerald Legge, the 9th Earl of Dartmouth, and Raine McCorquodale.
Through Raine’s later marriage to John Spencer, William became the stepbrother of Diana, Princess of Wales.
After the wedding, Diandra became the Countess of Dartmouth.
What Her Life Looks Like Today
Diandra Luker is no longer best described only as Michael Douglas’s first wife.
She is a film producer and the mother of four children.
She also has a long history with Mallorca.
Since 2025, she has been married to the 10th Earl of Dartmouth.
Her day-to-day life stays fairly private.
Most new coverage now comes from major family news, film history, or her Mallorca ties.
Why Her Story Still Draws Interest
People still search for Diandra Luker because her life connects several well-known stories.
Her first marriage links her to Michael Douglas and the wider Douglas family.
Cameron keeps that family connection alive.
Her film work gives her a career of her own.
Her children and Mallorca history add more depth to the years after the divorce.
The 2025 wedding also added a new chapter that many older profiles do not include.

Michael Douglas may be the reason many readers first know her name, but he is not the whole story. Her film work, four children, Mallorca ties, and new marriage give a fuller picture of who she is today.
