Recently, Song Hye Kyo's label UAA filed a lawsuit against the jewelry brand, claiming, "The brand has used Song Hye Kyo's images and video clips for advertisements. They made no requests of permission to validate Song Hye Kyo's rights. When issues regarding validation of rights came up, the brand requested to re-sign Song Hye Kyo as a brand model, but she has no interests in re-signing. We are not filing this lawsuit simply to receive monetary compensation, and if we do receive it, we will donate the amount." 

To this, the jewelry brand has responded with, "We formerly drew up a contract with the production team of 'Descendants of the Sun', including usage to images and video clips of the drama for advertisement purposes. We did not create any advertisement footage ourselves with Song Hye Kyo, so we do not see it as violating her rights." Song Hye Kyo was also seen wearing 'J.Estina' brand-wear as a part of product placement for 'Descendants of the Sun' throughout the drama. 

But 'Descendants of the Sun' has spoken up against the jewelry brand, stating, "In the case that the brand decides to use images and video clips of the actress outside of the drama, they should request permission from the actress."
