Sistar‘s Hyorin delivers exciting news together with her debuting as a solo artist with a full album.

Renowned American musician, singer, and songwriter Stevie Wonder will be a guest at the “2013 Mnet Asian Music Awards”, which will take place on November 22, 2013 at AsiaWorld-Arena in Hong Kong. According to sources, he and Hyorin will have a special performance.

It is a mystery how the two managed to squeeze in secret practice sessions (if they even did) into their busy lives. They will be singing Stevie Wonder’s classic hit, “I Just Called to Say I Love You.”

MAMA is very famous for their special and memorable performances. This year, the awesome lineup includes the Norwegian group and internet sensation Ylvis, who will be doing a collaboration with Crayon Pop, Swedish electro-pop duo Icona Pop, and the controversial Paris Hilton. We can also expect different musical numbers from other K-Pop artists.
