Mirta Miller’s romantic life continues to attract interest because of her past relationship with Alfonso de Borbón, Duke of Cádiz, one of the most prominent figures in Spanish aristocratic society. The Argentine-born actress discussed their relationship during a television interview in February 2024, recalling the years they spent together and the emotional impact of losing him.

Miller, who became a familiar face in Spanish cinema during the 1970s, has generally kept her personal relationships away from public attention. Although her romance with Alfonso remains well documented, there is no reliable recent confirmation that she currently has a boyfriend.

Who Is Mirta Miller’s Boyfriend?

Mirta Miller has not publicly identified a current boyfriend in recent verified reporting.

The actress, born on August 16, 1948, is 78 years old as of November 2026. Her romantic history has attracted attention because of her relationships with prominent figures in European society.

Her best-known relationship was with Alfonso de Borbón y Dampierre, the Duke of Cádiz and a grandson of King Alfonso XIII of Spain.

The couple became romantically involved following the breakdown of Alfonso’s marriage to Carmen Martínez-Bordiú.

Their relationship remained relatively discreet because of Alfonso’s family circumstances and the attention surrounding his aristocratic background.

Although some online biographies identify Manuel Degano as Miller’s spouse, reliable information about the timing and present status of that relationship is limited.

Consequently, there is insufficient verified evidence to establish whether Miller is currently dating anyone.

Mirta Miller’s Relationship With Alfonso de Borbón

Mirta Miller and Alfonso de Borbón shared one of the most widely discussed relationships of her personal life.

Alfonso was born on April 20, 1936, and belonged to the Spanish branch of the Bourbon royal family.

He married Carmen Martínez-Bordiú, granddaughter of Spanish dictator Francisco Franco, in 1972.

The marriage attracted considerable attention because of the families involved.

However, the relationship eventually deteriorated, and Carmen became romantically involved with French antiques dealer Jean-Marie Rossi.

Miller later explained that she met Alfonso during the late 1970s, before his marriage had completely ended.

Their romantic relationship developed after his separation from Carmen.

According to Miller, Alfonso initially pursued her, and their relationship remained private because neither wanted unnecessary publicity.

The couple did not marry or establish a permanent shared household.

Nevertheless, Miller maintained that their relationship was serious and continued until Alfonso’s passing in 1989.

What Did Mirta Miller Say About Alfonso de Borbón?

Mirta Miller spoke openly about Alfonso during a February 2024 appearance on the Spanish television programme Y ahora Sonsoles.

The interview marked approximately 35 years since Alfonso’s passing.

Miller recalled their relationship with considerable emotion and explained that she had never completely forgotten him.

She described Alfonso as a natural and sincere person, although their romance was complicated by his family responsibilities and public position.

The actress also discussed his relationship with his children and the difficulties he experienced following the breakdown of his marriage.

She recalled witnessing his grief after his eldest son, Francisco de Asís, was killed in a road accident in 1984.

Miller explained that Alfonso was deeply affected by the tragedy.

Her comments offered a rare personal perspective on a man whose private life had frequently appeared in Spanish society reporting.

Did Mirta Miller and Alfonso de Borbón Plan to Marry?

Mirta Miller and Alfonso de Borbón never married.

However, their relationship was serious enough for Alfonso to discuss the possibility of having a child together.

During a 2014 interview, Miller recalled that Alfonso had asked whether they could have a baby.

She admitted that the idea frightened her at the time.

Their relationship was complicated by Alfonso’s previous marriage, his children and the considerable public interest in his family.

Miller also explained that she was reluctant to become involved in the responsibilities associated with his aristocratic position.

Her relationship with Alfonso later became the subject of the 2004 biography Mirta Miller: La mujer que no quiso ser Borbón, written by Horacio Otheguy.

The title reflected her decision not to pursue a formal place within the Bourbon family.

Who Were Mirta Miller’s Previous Boyfriends?

Mirta Miller has discussed three significant romantic relationships during her life.

In a 2014 interview, she identified her first boyfriend as Alberto, whom she dated while living in Argentina.

She subsequently became involved with Frenchman Bernard Delagrange.

According to Miller, Delagrange passed away in a road accident while still relatively young.

Her relationship with Alfonso de Borbón followed.

Miller described Alfonso as one of the most important people in her life and acknowledged that his sudden passing had a lasting emotional effect on her.

Although she has been linked to other individuals in entertainment reporting, she has not publicly confirmed an extensive dating history.

Her own recollections suggest that she regarded only a small number of relationships as particularly meaningful.
