Lena Kallersjö: Björn Ulvaeus, Family Life, and Her Story

Lena Kallersjö was the longtime second wife of ABBA co-founder Björn Ulvaeus. They married in January 1981, raised two daughters together, and stayed married for more than four decades before separating in 2022. She died in January 2026 at age 76, with Ulvaeus later saying he missed her deeply.

Her name is often tied to ABBA because of that marriage, but her story also belongs to the quieter family life that developed around one of pop music’s biggest careers. Lena Kallersjö shared years that stretched from ABBA’s final recording period through the success of Chess, Mamma Mia!, the band’s reunion era, and a growing family with children and grandchildren.

A Life Connected to the Swedish Music World

Before she became part of the Ulvaeus family, Lena worked in Sweden’s music world. Contemporary accounts describe her as a music journalist, and older interviews with Björn place her around people connected to the record business in Stockholm.

That background helps explain why their paths crossed naturally. She was not entering an unfamiliar world when she met one of ABBA’s songwriters. She already knew people around the Swedish music scene and had social connections within the same circle.

Björn had recently separated from Agnetha Fältskog when he and Lena grew close. In a later interview with The Guardian, he said he met his future wife at a party shortly after the end of his first marriage. The relationship moved quickly, and the pair married in January 1981.

Marriage During ABBA’s Final Original Era

The timing placed Lena Kallersjö beside Björn during a major turning point in his career. ABBA had already become one of the world’s biggest groups, but the personal relationships inside the band were changing fast.

Björn and Agnetha had divorced. Benny Andersson and Anni-Frid Lyngstad were also moving toward the end of their relationship. At the same time, ABBA continued recording music and released The Visitors in 1981.

Lena’s marriage to Björn therefore began during a period when his private life and public work were both changing. She became part of a household that was connected to global fame while trying to build a stable family away from the stage.

The couple had two daughters, Emma and Anna. Björn also had two children, Linda and Peter, from his marriage to Agnetha. Over time, that created a blended family that stayed important to him even after his second marriage ended.

Family Life Away From the ABBA Spotlight

Lena Kallersjö never became a celebrity in the same way as the four ABBA members. She appeared beside Björn at public events over the years, but most of her life remained centered on family rather than performance.

That difference gave the marriage its own shape. Björn remained highly visible through songwriting, business projects, musicals, and later ABBA-related work. Lena was part of that life without building a public career around the fame that surrounded him.

In interviews, Björn often spoke about family as an important part of his life after the intense years of ABBA. He and Lena spent years raising their daughters while his work moved into new areas beyond the band.

During the 1980s, the family also lived in England for several years before returning to Sweden. By then, Björn’s career had moved into projects such as Chess, which he created with Benny Andersson and Tim Rice.

The Years After ABBA

When ABBA stopped working together as a regular group in the early 1980s, Björn did not step away from music. Instead, he continued writing with Benny and moved into theater and larger stage productions.

That period eventually led to Kristina från Duvemåla and then Mamma Mia!, the stage musical built around ABBA songs. The success of Mamma Mia! turned into a global theater and film phenomenon.

Lena Kallersjö was beside him through all of those years. Their marriage covered not only the end of ABBA’s first chapter but also the period when its music found a new life on stage and in film.

By the time ABBA’s catalog was reaching younger generations through Mamma Mia!, the couple had already spent decades together.

Two Daughters and a Growing Family

Emma and Anna kept a lower public profile than their father. Still, they were part of a family that often came together for holidays and later for time with grandchildren.

That family connection became especially important when Björn and Lena announced their separation in 2022. Their joint statement made clear that the end of the marriage did not mean the end of the family relationship.

They said they would remain close friends and continue celebrating grandchildren’s birthdays and other family occasions together. After 41 years of marriage, the tone of the announcement was calm and personal rather than hostile.

For Lena Kallersjö, that statement showed how much of the marriage had become tied to a shared family life built over four decades.

The 2022 Separation

The couple announced in February 2022 that they had decided to go separate ways. The news came after 41 years of marriage.

It was a major personal change for Björn, especially because the announcement came during a new period of ABBA activity. The group had released Voyage in 2021, its first studio album in 40 years, and the ABBA Voyage concert experience was about to open in London.

Even with that new attention around the band, Björn and Lena kept the separation itself brief and respectful in public.

Ulvaeus later moved on with Christina Sas, whom he married in 2024. Lena remained part of the wider family story through their daughters and grandchildren.

Her Place in Björn Ulvaeus’s Life

Lena Kallersjö was with Björn for most of his adult life. Their marriage lasted far longer than ABBA’s original run as an active recording group.

She was there through years when his work changed from pop records to stage musicals, rights management, theater projects, film adaptations, and the eventual return of ABBA.

That makes her place in his story different from the short label of “ABBA star’s wife.” She shared the long middle chapter of his life, including the years when he moved beyond the band and built a new career around songwriting, theater, and business.

She was also the mother of two of his four children and part of the family structure he continued to speak about warmly in later years.

Her Death in January 2026

Lena Kallersjö died in January 2026 at age 76. Björn’s agent, Görel Hanser, confirmed the death to Swedish media and the German Press Agency.

A dpa report carried by Tagesspiegel said Björn spoke publicly after her death and expressed how much he missed her.

His reaction reflected the long history they still shared even after their separation. Four years had passed since the marriage ended, but their daughters, grandchildren, and decades together remained part of both lives.

The news also brought renewed attention to Lena herself. For many readers, it was a reminder that she had been part of the Ulvaeus family story for more than 40 years.

A Marriage That Spanned Several Eras

What makes Lena Kallersjö’s story unusual is the length of time it covers.

She married Björn when ABBA was still releasing new music. She remained beside him as the group entered its long break, as he built new work with Benny Andersson, and as Mamma Mia! became a worldwide success.

She was still part of his family life when ABBA reunited to record Voyage. By then, the music that had made Björn famous in the 1970s had become part of global pop history.

Across those decades, Lena Kallersjö remained a much less public figure than her husband. That contrast is one reason readers still search for her. She was closely connected to one of the world’s most recognizable music groups while keeping most of her own life outside celebrity culture.

Why Her Story Still Matters

It is easy to look at Lena only through Björn’s fame, but the length of their marriage makes her role much larger than that.

They built a family, raised two daughters, lived through several stages of an extraordinary music career, and later became grandparents. Their relationship survived the intense public attention surrounding ABBA and continued for more than four decades.

Even the way the marriage ended showed that family remained central. Their 2022 statement focused on friendship, grandchildren, and continuing to share important occasions.

When Lena died in 2026, Björn’s public words showed that the bond had not disappeared with the divorce.

Lena Kallersjö’s Lasting Place in the Ulvaeus Family

Lena Kallersjö will always be connected to Björn Ulvaeus and the larger ABBA story, but her most lasting role was inside the family they built together.

She entered his life at the end of the 1970s, married him in 1981, became the mother of Emma and Anna, and shared more than 40 years of family and professional change. Their relationship stretched from ABBA’s final original studio years to the band’s remarkable return decades later.

Her life also shows another side of celebrity history. Not everyone connected to a famous name builds a public identity around it. Lena spent much of her life close to global fame without becoming a performer herself.
