The annual WaterBomb Festival was held Friday and Saturday at Jamsil Stadium in Seoul.

On the first day of the event, K-pop stars, such as Hyolyn and Jessi, appeared as guests with performances that doubled the fun.

The second day was a blast as Black Pink members showed up on Sprite Island, the name of a stage at the event, in outfits that matched the soft drink brand’s colors. Jennie donned a green off-the-shoulder top with short pants, while Jisoo wore a green cropped blouse with white shorts.

Black Pink also held a dance performance. Activities involving water guns were held to beat the heat.
