Heechul has never been one to shy away from his feminine beauty, and even his co-stars blush when they see him.
Heechul and his Knowing Bros. co-star, Lee Sangmin, donned the popular sparkly pink kitty filter on Instagram and hilarity ensued.
Everything was going just fine and the 2 busied themselves with making funny faces for the camera.
And then, Heechul did something that made his co-star blush.
Right in the middle of the video Sangmin gives up and exclaims that Heechul is too beautiful and no wonder, just look at the enchantress!
