In a new interview with Forbes, the Iranian-born actor and fitness influencer shared that he was initially hesitant about filming the music video where he met the pop star back in 2016. Asghari, 27, explained that he had recently done a music video with the band Fifth Harmony and wasn't interested in doing another, but his friend convinced him. "I wanted to do TV, I wanted to do film," he said. "My acting strategy was kind of to go away from music videos. I didn't want to do more and be known as a music video actor, but a good friend of mine was working on a project and they referred me to the team that was picking out the leading role for 'Slumber Party.'
