Early Life and Family Background
Sebastiana Bierk was born in 2007 in the United States, entering the world at a time when her father was already internationally known for his high-energy performances, soaring vocals, and influence in the glam-metal and hard-rock scene. As the youngest of three children, she grew up surrounded by a family deeply rooted in creativity. Her father’s career in music and entertainment, combined with her mother’s advocacy work and wellness-driven lifestyle, created a household filled with expression, movement, and constant artistic energy.
Her family heritage extends further into the world of art and entertainment. She is the granddaughter of David Bierk, the celebrated Canadian painter known for his distinctive style and contributions to modern visual art. She is also the niece of Zac Bierk, a retired NHL goaltender, and Jeff Bierk, a respected photographer. With such a broad artistic and athletic lineage, Sebastiana’s early life was shaped by exposure to creativity and ambition.
Despite growing up around fame, her childhood was carefully protected. Her parents, especially her mother, maintained a boundary between family life and the public eye, ensuring that Sebastiana experienced a childhood grounded in normalcy despite her father’s celebrity status.

Education and Academic Journey
Education has played a key role in defining Sebastiana’s current path. She completed high school in 2025, and her senior year included a standout school project where she interviewed her grandmother about life in the 1970s—an assignment that subtly highlighted her growing interest in storytelling, style, and generational shifts.
After graduation, she moved to New York City to pursue higher education at the Fashion Institute of Technology (FIT), one of the world’s leading schools for fashion and creative business. She is studying Fashion Business Management, working toward her Associate of Arts and Sciences (AAS) degree, with an expected completion in 2029.
Her decision to study fashion aligns naturally with her upbringing in a visually creative family, while also forging an identity outside of music. FIT provides her with opportunities to work with emerging designers, gain industry experience, and build a portfolio in a space far different from her father’s loud, electrifying world of heavy metal.
Sebastiana Bierk Age, Height, and Zodiac
Born in 2007, Sebastiana Bierk is 19 years old as of 2026.
She stands tall—thanks to her father’s 6’3″ frame—with a naturally striking appearance. Although her exact height is not formally documented, she is described consistently as tall with a commanding presence.
Her blonde hair and expressive brown eyes echo the signature look of her father in his younger years, while her poised demeanor reflects the influence of her mother’s disciplined approach to wellness and fitness.
Physical Appearance and Public Image
From her teenage years into early adulthood, Sebastiana has developed a style that blends California ease with New York fashion influence. Growing up partly in Santa Monica and now living in Manhattan has given her an aesthetic rooted in both coastal and urban culture.
Her public image is understated. Unlike many celebrity children, she embraces privacy. Her social media—under handles like sebastiana777_—is minimal and carefully curated. She shares occasional glimpses into her academic life, creative interests, and fashion inspirations, but avoids personal controversies or sensationalism.
Her physical traits—long blonde hair, a tall slim frame, and expressive features—suggest a natural fit for the fashion world, but she appears more interested in the business side rather than modeling or performing.
Sebastiana Bierk Parents
Father: Sebastian Bach
Her father, born Sebastian Philip Bierk on April 3, 1968, is a Canadian-American singer best known for leading Skid Row during their most successful era from 1987 to 1996. His powerful vocals, towering stage presence, and rebellious glam-metal image made him one of rock’s most recognizable frontmen.
Beyond music, Sebastian Bach has acted on Broadway in productions such as Jekyll & Hyde, appeared in Gilmore Girls, Trailer Park Boys, and competed on The Masked Singer. His career has spanned four decades, including solo albums, major tours, television roles, and active involvement in the entertainment world well into his fifties.
As of 2026, he is 57 years old, married to Suzanne Le, and lives primarily in Las Vegas and Southern California. His net worth is estimated at around $10 million, accumulated from touring, royalties, acting, and television appearances.
Mother: Maria Aquinar
Maria Aquinar, often referred to publicly as Maria Bierk, met Sebastian Bach in the mid-1980s before his rise to fame. The two built a life together through the height of Skid Row’s success and married in 1992. Maria is known for her fitness-driven lifestyle, wellness advocacy, and occasional television appearances, including features connected to Sebastian’s projects.
Born around 1963–1964, she is now in her early sixties. She maintains residences in New Jersey and New York City and continues to share her interests in health, animal rights, and community advocacy through social platforms.
Her Parents’ Marriage and Divorce
Sebastian Bach and Maria Aquinar were partners long before their 1992 wedding, dating since the mid-1980s. Their marriage lasted nearly two decades and saw them through fame, touring schedules, relocations, and the births of their three children.
After years of challenges and lifestyle differences, the couple separated in 2010 and finalized their divorce the same year. Their split received media attention, particularly after Sebastian framed the separation as rooted in irreconcilable differences.
Despite the emotional strain, both continued to co-parent, with the children spending time with both parents. Maria remained a stabilizing force in their children’s lives while Sebastian’s demanding touring schedule continued.
Sebastiana, being only three years old at the time, grew up primarily with her mother, while also forming a close bond with her father and later with her stepmother.
