Sia Siberia was born on December 24, 1990, in a small town in Siberia, Russia, which later inspired her stage name. Growing up in a cold climate, she developed a resilient and independent personality. She moved to Moscow in her late teens to pursue modeling opportunities, initially working as a fashion and glamour model before transitioning into adult entertainment. Her striking blue eyes, pale complexion, and naturally athletic build quickly set her apart in the industry.
Sia entered the adult film industry in 2012 at the age of 21. Her first scenes were produced by European studios specializing in high‑glamour content, and she soon gained a loyal following for her intense performances and distinctive screen presence. By 2014, she had worked with major European and American production companies, including Brazzers and Reality Kings. Her ability to switch between sultry and playful roles made her a versatile performer.
Throughout her career, Sia Siberia received several nominations from the Adult Video News (AVN) and the X‑Rated Critics Organization (XRCO). In 2016, she won the AVN Award for Best Foreign‑Starlet, becoming one of the few Russian performers to earn that recognition. She also received a NightMoves Award nomination for Best European Performer in 2017. Her popularity extended to social media, where she amassed over 200,000 followers on Instagram and Twitter before her accounts were suspended due to platform policies.
Sia stands at 5 feet 5 inches (165 cm) with a fit, toned physique. She has natural C‑cup breasts, a small waist, and a distinctive array of tattoos, including a large floral design on her right shoulder and a geometric pattern on her left forearm. Her icy blonde hair and sharp features contribute to her “icy” on‑screen persona. She has stated in interviews that her favorite physical trait is her eyes, which she considers her most expressive asset.
Outside of work, Sia is passionate about fitness and follows a strict workout regimen that includes weight training and yoga. She is also an avid painter, often sharing charcoal and oil artwork on her dedicated Instagram stories before it was taken down. In a 2018 interview with a European adult magazine, she mentioned that she enjoys reading classical Russian literature, particularly works by Fyodor Dostoevsky. She lives in Barcelona, Spain, with her two French bulldogs.
As of 2025, Sia Siberia has significantly reduced her on‑camera work, focusing instead on producing and directing content for her own premium niche sites. She occasionally collaborates with select European studios. Her influence on the European adult scene is noted for bridging the gap between mainstream glamour modeling and hardcore adult content, inspiring a generation of Eastern European performers to enter the industry with an emphasis on high‑production value. She remains active on OnlyFans and private fan platforms, where she interacts directly with her base.
