The viral video is bound to grace the TikTok scene, as many fans are calling for Britney's priceless post to become a dance challenge. User @michaelcostello wrote, "This is so cute it should be one of those challenges!"

Despite the seemingly cheeky post, some fans are still suspicious of Sam Asghari's role in Britney's life. Ever since the release of the Framing Britney Spears documentary, the #FreeBritney movement is stronger than ever. Fans still believe that the star is being held hostage in her conservatorship which is controlled by her father, Jamie Spears. While Asghari did speak out against Jamie recently on an Instagram story, calling him a "total d*ck," fans are still skeptical of his intentions.

One Instagram user wrote, "He’s (Sam Asghari) probably the one who wrote the caption..." regarding Britney's birthday post. "It has been said before that she doesn’t manage her Instagram," another Britney fan responded.
