The Korean celebrity wedding of the year in 2017 was undoubtedly the nuptials of Song Hye Kyo to Song Joong Ki, an event attended by many of their friends who also happen to be big stars in their own right. A pair of such friends went above and beyond as a guest and collaborated to perform a love song piano duet for the newlyweds at their reception, and it’s none other than cutie pies Park Hyung Sik and Park Bo Gum. The first pictures are out of the two talented stars serenading the newlyweds at their wedding, surrounding by other guests taking videos and pictures because who can blame them. Even stars get star-struck as well, right, and goodness it’s just too sweet to see these two big stars doing something so personal that also took effort since they had to have met up to practice beforehand. I’m sure their friendship with Song Hye Kyo and/or Song Joong Ki made it all so meaningful and worth it.
