Maria Aquinar is known chiefly as the first wife of Skid Row frontman Sebastian Bach — she’s not a public figure in her own right, and her limited public profile is essentially built around that 18-year marriage, their three children, and the reality-TV glimpses of that life on VH1’s I Married… in the mid-2000s. She’s sometimes credited under her married name, Maria Bierk — same person, different name, which is a common source of confusion online.
Sebastian Bach is no longer married to Maria. They separated in April 2010, divorced in 2011, and he has been married since to Suzanne Le, whom he wed in August 2015. So what happened to Bach’s first wife, in short: she and Bach split after 18 years together, and she has stepped back from public life since — she and Bach are not still married, and she has not remarried publicly as far as reliable reporting shows.
Here’s what’s actually confirmed about her — and what’s just widely repeated online without a real source.
Who Is Maria Aquinar?
Her full name is Maria Sandra Muir Aquinar. She’s Canadian and was born in December 1963 (some sources say the 23rd, others the 26th — there’s no confirmed original source pinning down the exact date, so take any specific birthday you see online with caution).
Little reliable detail exists about her childhood, family background, or life before she met Bach. That’s consistent with how she’s lived since: she has never sought media attention on her own and gives few, if any, interviews.

Meeting Sebastian Bach
Maria and Sebastian Bach met in the mid-1980s, before he joined Skid Row and before either of them was famous. She was already with him by the time Skid Row broke through in the late 1980s with hits like “18 and Life” and “I Remember You,” which meant she went from an ordinary life to touring, media coverage, and public scrutiny fairly quickly.
Marriage and Children
Maria and Sebastian married on July 26, 1992. They had three children together:
- Paris Francis Bach, born in March 1988 — before the marriage
- London Siddhartha Halford Bach, born January 17, 1994
- Sebastiana Maria Chantal Bach, born July 15, 2007
The marriage lasted 18 years. Throughout it, Maria stayed largely out of the spotlight relative to her husband, focusing on raising their children while he toured and recorded.
A 2026 update on Paris: Sebastian has spoken publicly about Paris now playing drums in his touring band, telling a podcast in early 2026 that he missed much of his son’s childhood while on the road and values the time they now spend together touring.
TV Appearances
Maria and the family appeared on VH1’s I Married…, a reality series about celebrity marriages that ran from 2003 to 2005 (their episode aired in 2004). Sebastian separately appeared on VH1’s Supergroup, a show about a temporary band project with musicians including Ted Nugent and Jason Bonham — that show centered on the band, not on spouses, so it’s inaccurate to describe it as one of Maria’s own TV credits.
Beyond I Married…, there isn’t reliable documentation of a modeling career or other entertainment work attributed to Maria specifically. Some sites describe her as a “model,” but none point to an actual campaign, agency, or credit — so this should be treated as unconfirmed rather than repeated as fact.
The Divorce
Sebastian and Maria separated in April 2010. Sebastian announced the divorce publicly around New Year’s Eve 2010, telling TMZ their “differences at this point are irreconcilable.” The divorce became final in 2011.
Bach later spoke candidly about what strained the marriage: the 2010 publication of The Last Living Slut: Born in Iran, Bred Backstage, a memoir by Roxana Shirazi that included stories about his behavior on the road, and the broader effect of internet culture and online gossip on a marriage that had started years before social media existed. Bach has said he disputes specific claims in the book but acknowledged its publication, combined with years of online speculation about his private life, took a real toll.
Life Since the Divorce
This is where the reliable information runs out. Numerous sites report that Maria became a vegan lifestyle and wellness advocate after the divorce, that she lives in New Jersey, and that she’s involved in animal rights or fitness advocacy. These claims appear, in nearly identical wording, across dozens of low-quality biography sites — but none of them cite an actual source: no interview, no social media account, no organization she’s affiliated with, no event she’s attended. That pattern is a strong sign the claim originated once, unsourced, and has simply been copied and reworded across the internet since.
The same goes for her height, weight, body measurements, and a net worth figure sometimes quoted as roughly $500,000 to $1 million — none of it traces back to anything verifiable.
What can be said with more confidence: she has stayed almost entirely out of public life since 2010, has not given notable interviews about her post-divorce years, and appears to prioritize her children’s privacy — all three of whom have avoided public attention themselves.
Sebastian Bach’s current wife is Suzanne Le, whom he married in August 2015. Her exact age isn’t something I can confirm from a reliable primary source — some sites list a birth year around 1972, which would put her in her early fifties, but that figure comes from the same kind of unsourced biography pages that got so much of Maria’s information wrong, so it’s worth treating as an estimate rather than a confirmed fact.
Conclusion
Maria Aquinar’s documented story is fairly simple: a private Canadian woman who was with Sebastian Bach from before his fame through 18 years of marriage, raised three children largely out of the spotlight, and stepped further back from public life after their 2010 divorce. Much of what circulates online beyond that — her exact birthday, her physical stats, a “wellness advocate” second act, a specific net worth — isn’t backed by any identifiable original source, and is worth treating as unconfirmed rather than fact.
