Wait, Britney Spears and her BF did how many takes of their workout video?

Britney Spears and her boyfriend, Sam Asghari, take their Instagram workout videos very, very seriously.

“He’s a trainer so everything has to be perfect,” the pop superstar, 36, told the Associated Press in an interview published on Thursday, May 10. “We probably did 40 [takes] and I hurt myself. It looked great. He did a good job and he edited it really, really well.”

The May 3 video shows Spears and the hunky fitness model, 24, powering through grueling exercises, including impressive variations of standard push-ups and sit-ups. It has since amassed more than 4.4 million views on the social media app.

The Grammy winner told the news agency that she usually asks sons, Preston, 12, and Jayden, 11, to shoot her photos and videos for social media because they perfect it in one take. But with her boyfriend, “I did it a million times and I swear it was horrible,” she joked. “When I do it just with my kids, it’s really fast.”

Spears has been working hard in the gym in preparation for her upcoming Piece of Me tour, which kicks off on July 12 in Washington, D.C. She said she’s looking forward to returning to the stage after her mega-successful Las Vegas residency because that’s where she feels most confident.

“I’m very sensitive and sometimes I just want to run away because I’m a very shy person,” she admitted to the AP. “I think energy is contagious and when I get on stage with the dancers, we all kind of vibe off each other. We feel the same energy and we connect. … [Performing is] a boost to my confidence. It’s like an alter-ego type thing. Something clicks and I go and turn into this different person. I think it’s kind of a gift to be able to do that.”

The “Gimme More” singer and Asghari began dating in late 2016 after meeting on the set of her “Slumber Party” music video, in which he starred as her love interest.

“Britney swore she was done with relationships, but then Sam came along,” a source told Us Weekly exclusively in February. “She’s very happy in her relationship. She has a consistent routine and she’s doing what she does best. Life is good for Britney.”
