Tony An's straightforward comment about Hyosung's changed appearance made Hyosung feel flustered. 

On the November 29 installment of MBC Every1 'Video Star,' Tony An and Hyosung discussed her past looks. The MCs exposed Tony An's past comment, saying, "Tony An said that Hyosung used to be chubby and now she has transformed into a different person after losing weight." Hyosung responded, "Really? Me?" Tony An tried to explain, "No, I didn't say it like that."

Tony An explained that he is meeting Hyosung for the first time in seven years, that it has been a long time. He joked, "You look completely different," and one of the MCs added, "Did she transform into a different person?" making everyone laugh. 

The veteran singer then explained, "It feels weird to just call her, Hyosung, because now she is a lady."
