With her hair worn loose, the her outfit is accessorised with several statement necklaces and rings while she is also seen brandishing a metallic backpack in the video.

Beyoncé is later seen with husband Jay Z, who gently pats his wife's baby bump as he sits alongside her in the front row at a basketball game.

The Halo star appears to be eager to document her pregnancy style, and earlier shared a photo on her website from the Wearable Art Gala in Los Angeles on Saturday ( 29 April) alongside Jay Z.
