The sketches celebrate the maternal journey of the songstress, featuring her growing belly. The color gold and yellow were reminiscent of her “Hold Up” music video, where she appears as Oshun, a Yoruba water goddess of female love and fertility.

On her website, the Grammy-award winner and mom-to-be revealed photos with her daughter, Blue Ivy, 5, and mother, Tina Lawson. Both were dressed in the gold regalia the singer wore during her awards show performance.
