In December 2016, Sam started dating pop icon Britney Spears. Rumors spread about them dating as early as November 2016 after Asghari posted photo of him and Britney Spears on Instagram account. The photo recirculated after Asghari deleted the photo from his account. They met on the set of her music video for the song "Slumber Party" featuring Tinashe. When their relationship was discovered, many paparazzi were surprised that Sam opens the car door for Britney, which is a typical custom for Persian gentlemen.
