Maria Aquinar is best known as the former wife of Sebastian Bach, the Canadian rock singer who became famous as the lead vocalist of Skid Row. While her husband performed in front of thousands of fans, Maria experienced a different side of the music industry, including family responsibilities, television appearances and the pressures that came with fame.
Their relationship began before Bach became a household name in rock music. They went on to spend more than two decades together and welcomed three children before separating in 2010.
Although Maria was once a familiar face at entertainment events, she has received far less public attention since their marriage ended. Her story continues to interest fans who want to learn about her background, family, career and life after leaving the spotlight.

Who Is Maria Aquinar? Early Life and Background
Maria Aquinar, also known as Maria Bierk, became widely recognised through her relationship with Sebastian Bach. She is often described in online biographies as a former model and television personality.
Several biographical websites list her full name as Maria Sandra Muir Aquinar and her birth date as 23 December 1963. However, reliable public records confirming these details are limited.
Much of her childhood remains unknown. There is little trustworthy information about her parents, siblings, education or the place where she grew up. Unlike many people associated with the entertainment industry, she has not shared an extensive public account of her early years.
Maria Aquinar’s modelling career is another part of her background that attracts attention. Various websites describe her as having worked as a model before becoming known through Bach.
However, specific modelling agencies, major advertising campaigns and magazine contracts have not been widely documented. This makes it difficult to establish the full extent of her professional work.
What is clear is that she became part of the rock music world during a period when heavy metal was enjoying enormous popularity.
Her relationship with Bach brought her into contact with musicians, television producers and entertainment personalities. Over time, she became known to fans who followed both his professional career and his family life.
Maria Aquinar and Sebastian Bach: A Relationship Before Fame
The love story between Maria and Sebastian Bach began in the mid-1980s. At the time, Bach was still a young singer hoping to make his mark in the music industry.
He had not yet achieved the international success that would arrive with Skid Row.
The band became one of the most recognised names in hard rock during the late 1980s and early 1990s. Songs such as 18 and Life, Youth Gone Wild and I Remember You helped establish Bach as a major rock vocalist.
Maria had been part of his life before that success arrived.
The couple reportedly began dating around 1985. Their relationship developed through the early stages of Bach’s musical career, including the years when he was building his reputation as a performer.
They married on 26 July 1992, several years after they first became involved.
By then, Bach was already a recognised figure in rock music. His career involved recording, touring, interviews and public appearances.
Being married to a successful musician brought opportunities for public attention, but it also meant dealing with an unpredictable working schedule.
Concert tours could keep Bach away from home for long periods. His professional commitments continued while the couple built their family.
Maria occasionally attended public events with her husband, appearing beside him at entertainment gatherings and industry functions.
Their marriage lasted for approximately 18 years, while their relationship as a whole stretched across more than two decades.
For fans who followed Bach’s career from the beginning, Maria became a familiar part of his story.
Maria Aquinar’s Children and Family Life
Family played an important role in Maria’s years with Sebastian Bach. The couple welcomed three children together: two sons and a daughter.
Their eldest son, Paris Francis Muir Bach, was born on 4 March 1988. His arrival came several years before his parents married.
Their second son, London Siddhartha Halford Bach, was born on 17 January 1994.
The couple later welcomed their daughter, Sebastiana Maria Chantal Bach, on 15 July 2007.
The children grew up with a father whose professional life was closely connected to the entertainment industry. Touring, recording and public performances were regular parts of Bach’s career.
Despite their father’s fame, the children have not all followed the same path.
Paris Bach’s Connection to Music
Paris has pursued music and is known for his work as a drummer. He has also performed with his father’s solo band.
This connection has attracted interest from fans who remember Sebastian Bach’s earliest years with Skid Row.
Seeing father and son involved in music adds another chapter to the family’s history.
London and Sebastiana have generally attracted less media coverage. Reliable information about their personal interests and everyday lives remains limited.
Growing Up Around Rock Music
The Bach family experienced a lifestyle that was different from that of many households.
Sebastian’s work brought him into contact with international audiences, musicians and television personalities. At the same time, ordinary family responsibilities continued away from concert stages.
Maria was part of that family setting throughout much of his career.
Although the public saw occasional photographs and television appearances, most details about how the family managed everyday life remained outside the headlines.
Their three children continue to be an important connection between the former couple.
Modelling, Television Appearances and Public Recognition
Maria Aquinar never developed the same level of public fame as her former husband. Nevertheless, she appeared in entertainment programmes that allowed audiences to see parts of their relationship.
One of her most notable appearances was in the VH1 reality programme I Married Sebastian Bach.
The programme aired in 2004 and offered viewers a look at life around the rock singer, including his relationship with Maria and the preparations for touring.
At the time, Bach described Maria as both his wife and manager.
This detail showed that her involvement in his professional world extended beyond simply attending public events.
The programme gave fans a chance to see the couple together outside the usual concert setting.
Maria also appeared in connection with Supergroup, a VH1 reality series broadcast in 2006.
The programme featured Sebastian Bach alongside several other rock musicians, including Ted Nugent, Scott Ian, Jason Bonham and Evan Seinfeld.
While the musicians were the main focus, Maria appeared during the series as part of Bach’s wider personal story.
She is also credited under the name Maria Bierk in entertainment databases, including for Sebastian Bach: Forever Wild.
These appearances explain why some online biographies describe her as a television personality.
However, she did not establish a widely documented independent career as a television presenter or actress.
Most of her best-known screen appearances were connected to Bach’s work.
The distinction matters because her public recognition came largely through her relationship with the singer rather than a long list of individual entertainment projects.
Why Did Maria Aquinar and Sebastian Bach Divorce?
After spending many years together, Maria Aquinar and Sebastian Bach separated in April 2010.
Their separation became public in December of that year when Bach announced that the couple had been living apart for several months.
He explained that they had tried to resolve their problems for the sake of their family but had been unable to overcome their differences.
The announcement marked the end of a marriage that had lasted approximately 18 years.
Their divorce was widely discussed during 2011, although a precise finalisation date is not consistently established in reliable public records.
What Caused Their Separation?
The breakdown of the marriage attracted attention because Bach had spoken publicly about his relationship over the years.
In later interviews, he discussed the difficulties surrounding the separation and his own behaviour during the marriage.
He initially made comments about how information shared online had affected his relationship.
However, he later clarified those remarks and accepted personal responsibility for the breakdown of the marriage.
Maria did not provide an equally detailed public account of the separation. For that reason, it would be unfair to present speculation about their relationship as established fact.
What is publicly known is that their long marriage ended after they were unable to settle their differences.
Where Is Maria Aquinar Now?
Following the divorce, Maria gradually became less visible in entertainment coverage.
She has not maintained the same level of public attention that surrounded her during her marriage.
Some online profiles connect her with fitness, veganism and healthy living. However, there is limited reliable information confirming her current work or everyday activities.
Her exact place of residence and present relationship status are also not clearly established through trustworthy public sources.
As of 2026, there have been few well-documented public updates about her activities.
Sebastian Bach, meanwhile, has continued performing and recording music. He married Suzanne Le in 2015.
Although Maria’s name still appears in stories about Bach’s past, her own recent life remains largely outside public view.
For someone who once appeared on television alongside one of hard rock’s biggest personalities, that is a noticeable change.
Conclusion
Maria Aquinar became known to rock music fans through her long relationship with Sebastian Bach, but her story covers much more than a celebrity marriage.
She was with Bach before his biggest success, shared nearly two decades of marriage with him and raised three children during some of the busiest years of his career.
Her television appearances gave audiences occasional glimpses into their family life, while their separation in 2010 marked a major change for both of them.
Today, much of Maria’s life remains outside public attention. Although fans continue to search for information about her, there are still many details she has not publicly shared.
Her connection to one of rock music’s most recognisable voices remains part of her history, but it does not tell the whole story of her life.
