Britney Spears and her hunky fitness trainer and model beau Sam Asghari may be a staple on Instagram, but it was pure serendipity that brought the PDA-loving pair together. And their meet-cute almost didn't happen entirely!

Speaking to Men's Health magazine, Asghari, 24, explained how a last minute casting two years ago drew him into the pop star's circle.

Asghari shared that in October 2016, he woke up to two frantic voicemails from his agent asking if he could make it to the "Slumber Party" music video set the next day to play Spears' love interest.

"I got a call at midnight," he told the magazine, noting that music video leads are usually cast weeks in advance. “It went through so much to get to me. I don’t know if it’s some sort of a blessing or just meant to be.”

“I was excited that I get to meet one of the biggest artists of all time. I had butterflies," he added, admitting that he ended up flirting with the Princess of Pop while on set. "She said, ‘Hi, I’m Britney,' and I said, ‘I’m sorry. What’s your name again?’ I tried to be funny. I don’t think anybody got it."

The pair hit it off though, conversing during filming breaks and exchanging numbers at the end of the shoot—which led to a sushi date soon after.

"After the video came out, nobody knew we were dating. I don’t think [she or I] had the intention to just be friends," Asghari shared.

The model and aspiring actor, whose favorite Spears song is "Stronger," added that the performer "motivates me more than anyone."

"It’s crazy how I can be humbled by a person like her. If I could be that humble when I’m that high in life, that would be the best thing," he said. “I grew up with three sisters, and my personality is just to be a supportive person for my family and she’s family. I’m always going to support her. She is another blessing that happened to me.”
