Maria Aquinar’s was born in December 1963
Maria Aquinar was born in December 1963, which makes her age 62 in 2026. She turns 63 later this year. Sources disagree on the exact day. Some list December 23 and others list December 26. Neither date is officially confirmed, so it is fair to say only that she was born in late December 1963.
Little is known about her childhood, family background, or education. She has not given long interviews about her early life. Reports describe her as reportedly American with a reportedly multiracial background, but she has not publicly discussed either point in detail. This is common for people known mainly as the partner of a celebrity.
How Maria Aquinar Met Sebastian Bach
Maria met Sebastian Bach in the mid-1980s, before he became a household name. At that time, Bach was a young singer working his way through the hard rock scene. He joined Skid Row in 1987, and the band rose quickly after that.
The exact place and moment they met have not been widely documented. What is clear is that the relationship began before his fame. Their first child arrived in 1988, shortly after Bach joined Skid Row. That timeline shows Maria was part of his life while his music career was still taking shape, not only after he became a star.
Maria and Sebastian’s Marriage married on July 26, 1992
Maria and Sebastian Bach married on July 26, 1992. By then, Skid Row was one of the biggest names in heavy metal. The band’s second album, Slave to the Grind, had reached number one on the Billboard 200 chart in 1991. Billboard is the main US music chart.
The marriage lasted through several big changes in Bach’s career. The list below shows the key points in order.
- 1987: Bach joins Skid Row as lead singer.
- 1992: Maria and Sebastian marry on July 26, 1992.
- 1996: Bach leaves Skid Row and begins a solo path.
- 2000s: He keeps touring and appears on television.
Through these years, Maria was part of the rock star’s family. She appeared at some public events and on TV, but she generally stayed out of the tabloid spotlight. The couple raised their children while Bach traveled for tours and recording.

Maria Aquinar on TV

Why Maria Aquinar and Sebastian Bach Divorced
No single reason for the split has been confirmed by either side. The timeline is clearer than the cause. The ordered list below shows what is known.
- July 26, 1992: The couple marries.
- 2010: Maria and Sebastian separate after about 18 years of marriage.
- 2011: The divorce is finalized.
Because no official explanation exists, many claims online are only internet rumors or public rumors. Treat them with caution. Long marriages in the music world often face strain from touring, time apart, and outside pressure from fans and media. That is a general pattern, not a confirmed reason for this couple. The safest statement is that the marriage ended in divorce in 2011 and that both sides moved on quietly.
Sebastian Bach’s Response to the Divorce
Sebastian Bach’s response to the divorce was reportedly measured. He has spoken publicly about his family and his children over the years, and reports suggest he kept comments about the split short and centered on the kids. He has not turned the divorce into a public fight, which is part of why the story stayed low-key.
This calm tone matches how the couple handled their private life. Neither has been known for airing details, and that helped limit the effect of public rumors.
Maria Aquinar’s Life After Divorce
After the divorce, Maria Aquinar returned to a quieter routine. Her youngest daughter was still a small child, so being a mother was a main focus. Reports say she leaned into healthy living and personal well-being, including a fitness-focused and vegan lifestyle.
The list below shows what her life after the divorce is reported to include.
- Family first: Raising her children and staying close to them.
- Fitness and wellness: Regular exercise and healthy habits, in line with her reputation as a fitness and wellness advocate.
- Vegan lifestyle: A plant-based diet, reported as part of her daily choices.

She has not tried to profit from her ex-husband’s fame, which fits the private and calm routine reported for her.
Sebastian Bach’s Life After Maria
Sebastian Bach kept his music career going after the divorce. He continued to tour and release solo albums, including Angel Down in 2007 and Give ‘Em Hell in 2014, and he stayed popular with rock fans around the world.
In his personal life, Bach married Suzanne Le Bach in 2015. Suzanne Le, now known as Suzanne Le Bach, became his wife after his first marriage to Maria ended.
