Girls' Generation's Taeyeon recently revealed that Super Junior's Heechul is the best at imitating others.

JTBC interviewed all the K-Pop singers who will be featured on the show "Hidden Singer 3" and Taeyeon was asked, "Have you seen people imitate you?" She replied, "I've never seen anyone do it seriously. My friends and coworkers just do it for fun."

When she was asked which of her label-mates does the best impersonation, she immediately picked one of Super Junior's members, saying, "Heechul oppa is the best." 

The interviewer also asked Taeyeon which song she finds hardest to sing? She chose "Can You Hear Me?" and explained, "The beginning part is hard because you have to sing it like you're speaking."  She then gave a short sample of the song. Taeyeon added, "Men really like 'Can You Hear Me?' Heechul oppa imitates that song so much."
