Sam Asghari, an American model, actor, and fitness entrepreneur, first captured public attention as a fitness model before gaining wider recognition through his relationship with pop icon Britney Spears and his subsequent forays into acting. Born Hesam Asghari in Tehran, Iran, on March 3, 1994, he immigrated to the United States with his family at a young age, settling in Los Angeles, California. He was raised by his parents, Mike and Fatima Asghari, and developed a passion for fitness and bodybuilding during his teenage years, which laid the foundation for his future career.

His professional journey began in the fitness industry, where he worked as a personal trainer and built a significant following as a fitness model on social media. This success led him to establish his own business, Asghari Fitness, in 2020, a website offering personalized training programs. His chiseled physique and online presence also opened doors in entertainment, leading to appearances in music videos for artists like Fifth Harmony and Britney Spears for her "Slumber Party" single in 2016. It was on the set of this music video that he first met Spears, with whom he began a highly publicized relationship.

Asghari strategically leveraged his growing profile to pursue acting. He landed guest-starring roles on television series such as Black Monday, Hacks, and The Family Business, showcasing his comedic and dramatic range. His relationship with Britney Spears culminated in their engagement in 2021 and marriage in June 2022, an event that placed him firmly in the international spotlight amidst the intense media scrutiny surrounding Spears's conservatorship battle. The couple announced their separation in August 2023, and their divorce was finalized in 2024.

Continuing to build his career independently, Asghari expanded his acting portfolio with a role in the second season of the popular reality competition series The Traitors in 2024. Balancing his entrepreneurial fitness ventures with his acting ambitions, he maintains a presence in the entertainment industry.
