Why did Alex Kingston leave Ralph Fiennes?

Marriage to Ralph Fiennes

Reason for divorce

The couple divorced in 1997. Kingston has never publicly detailed the exact cause, but she later told RTÉ (Irish national broadcaster) that the split was amicable and they remain on good terms.

Friendship after divorce

Kingston and Fiennes have shared professional spaces over the years. She noted in a 2024 interview with RTÉ that they have “genuine affection” for each other despite the separation.

Bottom line: The marriage lasted four years. Kingston and Fiennes divorced in 1997 but remain friends. For readers seeking closure on the split, the official reason stays private, but both parties consistently speak about each other with respect.

What illness did Alex Kingston have?

Diagnosis and treatment

In 2024, Kingston was diagnosed with womb cancer. She told BBC News (UK public broadcaster) that her treatment included a hysterectomy and radiation therapy. The cancer was found in her fallopian tubes and had not spread to her ovaries.

Impact on career

Kingston experienced a haemorrhage while performing on stage in 2024, which pushed her to seek medical help. She initially dismissed symptoms like bloating, achiness, and weight gain as age-related, according to an interview with People.

Public revelation

She went public with her diagnosis in 2025 to raise awareness. The Independent (UK news outlet) reported that her treatment finished toward the end of 2024.

Why this matters

Kingston’s story underscores a common trap: women in their 50s and 60s often attribute early cancer symptoms to menopause or aging. For the millions watching Strictly, her openness could prompt others to check persistent signs.

Kingston is not currently married. She wed German film director Florian Haertel in 1998, but reports indicate the couple have separated, though neither has confirmed a formal divorce.

Daughters

Kingston has two daughters with Florian Haertel. She has kept their names and ages mostly private, but she has mentioned them in interviews, including with People.
