'Superstar K4' winner Roy Kim recently met up with Psy backstage at the '2012 MAMA'.

Fans were eager to see the two stars finally meet face to face, not as a judge and contestant, but as one singer to another. This was Roy Kim's first encounter with Psy since last August after Psy was unable to continue judging 'Superstar K4' due to his overseas activities.

Prior to Roy Kim's performance at the awards ceremony, the singer visited Psy's dressing room and presented him with a small gift to show his gratitude to the former 'Superstar K4' judge. Psy was seen thanking him for the gift, and his positive energy created a lighthearted atmosphere.
