If you were wondering why people all over the Internet are filming themselves performing complicated choreography to the tune of an R&B track telling them to "turn around", "glide" and "drop it down", then you're not alone.
The answer is, of course, Beyoncé Knowles-Carter.
On Wednesday, Beyoncé shared her very first Instagram story, which featured videos of fans carrying out a new dance challenge to one of her latest songs.
One of the bonus tracks featured on the star's recently released Homecoming live album is a cover of "Before I Let Go", a song originally performed by American R&B band Maze in 1981.
The upbeat song has sparked a new social media craze, with many members of the Beyhive (Beyoncé's most dedicated fans) attempting to emulate the dance moves mentioned in the lyrics.
The lyrics go as follows: "Turn around, kick, then slide. And twirl that ass to the right, now. Ooh, bunny hop, bunny hop, drop, pop. Cross your legs, turn around and clap. Shuffle to the left, let's glide now. Ooh, drop it down, drop it down low, low."
Numerous superfans of Beyoncé have shared videos of themselves doing the "#BeforeILetGo" challenge on social media, some of which have even caught the attention of the Queen Bey herself.
In one of the videos, a toddler joins in with the dance as a young man and woman do their version of the choreography.
In another video, a man does the dance while standing on top of a red car.
Frankie Beverly, frontman for Maze and writer of "Before I Let Go", responded positively to Beyoncé's inclusion of the track on her live album, describing it as a "blessing".
"This is one of the high points of my life," he told Billboard.
“Girl you make me so proud and I love you. I also love that your new Netflix film Homecoming is informed by the black leaders, thinkers and poets who have paved the way for folks like us," Obama said.
