How stunning is too stunning?

Girls' Generation's Im Yoona and EXO's Kai (Kim Jong In) paired up for the February issue of ELLE Korea and left fans swooning with their rugged look.

Yoona was featured with a more somber facial expression all the while retaining a charismatic appearance. Kai, on the other hand, resonated pure mystery with an intense gaze straight to the hearts of anyone who glances at the cover.

This particular spread is a continuation of Jcontentree and SM Entertainment's participation in the Louis Vuitton and UNICEF 'Make A Promise' campaign.

Kai and Yoona aren't the first K-pop stars to participate in the campaign. Kai's bandmate Oh Sehun and Red Velvet member Irene (Bae Joo Hyun) were featured in CeCi magazine earlier this month.

Both spreads feature a silver Louis Vuitton necklace with a locket pendent symbolizing the 'Make A Promise' slogan and a matching bracelet of the same kind. It was reported that 40% of the proceeds garnered from these items will be donated to help children in need through UNICEF.

The February edition is expected to include a full pictorial in conjunction with an interview with the two mega-stars.

Meanwhile, EXO are busily preparing for their February tour of North American while the members of Girls' Generation are focusing on solo activities.
