Singer Ailee is in a panic after injuring her ankle just days on the day of her comeback.

On July 10, she injured her ankle while walking on the street. She has taken medication and is still trying to make it onstage for KBS "Music Bank."

Although she received treatment from the hospital, she is still not able to walk properly. She is feeling pain when wearing heels as well.

With many other TV show programs lined up this weekend, they are worried that her ankle might get worse.

On the other hand, Ailee released her new song, "U&I" today.

This song is currently at number 1 on various music sites.
