TVXQ star Changmin was the celebrity guest of honor at soccer star Koo Ja Cheol's wedding after putting in a surprise performance as a gift to the newlyweds.
The 25-year-old singer took to the stage at the luxe Sheraton Grande Walkerhill hotel in Seoul on Saturday June 22 to sing a congratulatory song for the FC Augsburg midfielder and his Jeju-born wife (whose name he has asked to remain anonymous).
"Congratulations on your wedding and I wish you a happy marriage and hope that you continue to make illustrious achievements abroad," the idol told the couple.
Koo, who captained the Korean national team at the 2012 London Olympics winning bronze, invited a host of famous friends to his wedding.

And Ki will have a wedding of his own next week, when he marries actress Han Hye Jin.
The 24-year-old central midfielder joked with reporters outside the ceremony venue: "Ja Cheol is getting married a week earlier than me, and many players of our age would also marry this year, so I think we'll all have a pretty strong performance next season."
