Not just the fans are admiring Taeyeon’s singing abilities but her co-singers, too! Girl’s Generation member wowed SHINee member Jonghyun when they are performing and promoting their duet “Breath,” under SM The Ballad.

In an interview on Mnet’s “Wide Entertainment News – The Music Interview” on February 18, Jonghyun praises Taeyeon’s singing ability and said, “Taeyeon’s voice is full of power and her way of expressing emotion through her voice makes me feel that she had experience the pain in love and life. You can almost feel it in your heart – and very few young singers can do that. She is very young and she has a lot of potential.”

When Jonghyun was comparing himself to Taeyeon, he admitted that he can’t help but felt envious. But we all know that singers are professionals, and even Jonghyun might have envy Taeyeon, he said he is hopeful to learn lot from their duet.
