Beyonce and her former Destiny'S Child bandmates Kelly Rowland and Michelle Williams have reunited to take on social media's 'Mannequin Challenge'.

The ladies recently got together to celebrate the second birthday of Kelly's son, Titan, and they decided to have a little fun by striking a pose for the Internet craze, in which participants do their best not to move while Rae Sremmurd's Black Beatles song pumps out in the background.

Kelly shared video footage of the best friends messing around on Instagram on Monday (07Nov16), with the clip showing Beyonce in the act of catching a ball from Michelle, while the Dilemma singer brandishes a long blue balloon as a baseball bat while they stand in what appears to be her son's playroom.

Their clip was set to the sounds of Lauryn Hill's Oh Jerusalem, and Kelly captioned the post with a series of party emojis.

They aren't the only stars getting in on the Mannequin Challenge - comedian Kevin Hart recruited his gym buddies for his attempt over the weekend (05-06Nov16) in a post which has since gone viral.

Meanwhile, Kelly has shared a few more snaps from her baby boy's big day, including one photo of Titan playing with toy cars with Beyonce's mom, Tina Knowles.

Little Titan turned two on Saturday (05Nov16) and his proud mom took to Instagram to express her love for her son by sharing a slideshow of images documenting his childhood so far.

"MY GREATEST BLESSING TITAN, I CAN'T BELIEVE ANOTHER YEAR HAS PASSED!" she wrote in the accompanying caption. "I AM SO PROUD OF YOU AND THANK GOD EVERYDAY FOR MAKING YOU MINE! DADDY & I LOVE YOU SO MUCH!"

Titan is Kelly's son with husband Tim Weatherspoon.
