The fun moment was captured with Kim's six-year-old daughter Chicago, who clung to her mother's hip throughout the video.

Kim looked as radiant as ever in her floor-length gown, which featured thin straps and a crisscross design with a dark stone medallion at the center.

The SKIMS mogul enhanced her look with open-toe black heels, a small gold handbag, and straightened raven-colored hair. Her full face of glowy matte makeup perfectly complemented her ensemble.
