It all began with Maria Aquinar standing backstage at a Skid Row concert, her heart pounding, watching Sebastian Bach belt the chorus of “18 and Life.” In that moment—flashing cameras, screaming fans—she stepped into a life she had never anticipated. Fast forward years later, she would walk away from that life to become a voice in health, fitness, and reinvention.
Today, when you hear Maria Aquinar, you don’t just think “rock legend’s wife”—you think resilience, wellness, and reinvention. In this article, you’ll follow her journey, discover lessons you can apply, and see how her story ties to fitness, vegan advocacy, and personal branding in the digital age.
Who Is Maria Aquinar?
Maria Sandra Muir Aquinar, often known also under the name Maria Bierk, rose to public attention mainly through her marriage to Sebastian Bach, the lead singer of the metal band Skid Row. They married on July 26, 1992, though their relationship began years earlier.
But that doesn’t capture the full picture. Maria also has credits in television and film: she’s credited (under “Maria Bierk”) in Supergroup (2006) and Sebastian Bach: Forever Wild (2004). Her identity extends beyond the shadow of her ex-husband, into modeling, wellness, and advocacy.

The Early Years & Rise Into Public Life
Let me rewind a bit. Maria’s early life is somewhat of a mystery—details about her family, upbringing, and education are sparse in public record. But what we do know is that her life shifted when Sebastian’s musical career took off.
In the mid-1980s, before Skid Row became a household name, Maria and Sebastian began their partnership. They navigated early struggles, artistic ambitions, and public scrutiny. When he broke through, Maria found herself suddenly in the spotlight. In essence: she grew into fame by association—but later worked to reclaim her own narrative.
Her appearances on reality shows like I Married… and Supergroup gave glimpses behind the curtain of life with a rock star, and also helped familiarize audiences with her personality beyond “the wife.”
Transition point: Fame arrived, but so did expectations—and challenges.
Marriage, Family & the Public Gaze
By public accounts, Maria and Sebastian had three children: Paris (born 1988), London (born 1994), and Sebastiana (born 2007). Notice how Paris’s birth predates their wedding—a detail often highlighted in media.
Their marriage (1992–2010) spanned nearly two decades.During those years, media often portrayed them as a “rock power couple,” with Maria seen at events, photo shoots, interviews, and alongside Sebastian on tours.
But being in the public eye has a price. Rumors, criticism, and scrutiny grow faster than any signature tour poster. Sebastian himself later attributed internet gossip and a controversial book to strain in their marriage.
“You can go online, and there’s a c**k chart … and find these chicks typing whatever they want,” Sebastian once said, blaming internet culture for some of their issues.
In late 2010, their marriage ended in divorce. They had tried to keep it together “for the sake of the family,” but ultimately chose separation.
Rebirth: Maria’s Reinvention Post-Divorce
If the end of her marriage was the closing of one chapter, what followed was a more personal opening. Maria transitioned. She leaned into what she wanted, rather than what the world expected.
Embracing Fitness & Wellness
Post-divorce, Maria began aligning more deeply with fitness, health, and vegan living. Many reports call her a “fitness and vegan advocate.” She used her platform to speak about wellness—not as a side gig, but as identity.
This shift is foundational: she repackaged herself not as “famous ex-wife,” but as a voice in wellness, authenticity, and balance. Her transformation resonates because it wasn’t forced—it was emergent.
Public Appearances, Media, & Identity
Maria’s presence in entertainment didn’t vanish; she remained involved through modeling, appearances, and media. Her work in Supergroup, for instance, allowed her to step in front of cameras in a context separate from Sebastian.
Gradually, the narrative shifted: Maria Aquinar was not just Sebastian’s spouse, but someone with her own mission, her own audience, her own voice.
