After announcing that legendary American singer and songwriter Stevie Wonder will be a guest at the “2013 Mnet Music Awards,” it has been announced that he will have a duet with Sistar‘s Hyorin for a special performance.

It is unsure how the two managed to have secret practice sessions, if they had them at all, but Hyorin and Stevie Wonder will have one of the highlight performance of the night. The two will be singing Stevie Wonder’s classic hit, “I Just Called to Say I Love You.”

“2013 MAMA” has always been known for their special collaboration, and it was already announced that Norwegian group and internet sensation Ylvis will be doing a collaboration with Crayon Pop.
