Britney Spears’ boyfriend, Sam Asghari, has been by her side for years — they met on the set of her 2016 music video for "Slumber Party." With Asghari playing such a big role in the Spears' life, fans are curious about details of his life, so what does he do for a living?

According to Harper's Bazaar, Sam Asghari works as a personal trainer and even runs his own business, Asghari Fitness. He has also worked as a model, and told Men’s Fitness that his sister actually got him into modeling.

"My sister said, 'I will take you to this audition, just come with me,'" Asghari said of his early modeling days. That audition landed him a runway show in Palm Springs, and more gigs, including a 2016 Super Bowl ad for Toyota Prius and a role in Fifth Harmony's "Work From Home" music video.
