On part 2 of the Kim Hee Gab and Yang In Ja special, Cheetah surprised everyone by putting aside rapping to sing instead. She said before getting on stage, "To be honest, I feel pressured by the 'Immortal Song' stage. Everyone performing is so talented. I want to put on stage that's very human and genuine."
She covered legendary singer Cho Yong Pil's hit song "Q" for a performance that fans have not seen before.
However, she wasn't able to defeat musical star Min Woo Hyuk, who took the final win.
