Taeyeon responded to a vicious hater online, who made accusations about her loyalty to Girls' Generation as well as alleged cosmetic surgeries.

On January 17, Taeyeon posted a series of selfies with some including Snapchat filters on Instagram. One netizen commented, "Seohyun promoted your solo song, so why aren't you promoting hers? You have no loyalty. Your face is melting because of your failed double eyelid and nose surgeries, so that's why you only post photos using a snowcam filter."

It seems the comment may have seriously bothered the Girls' Generation leader as she replied, "Yep. Look in the mirror." Taeyeon then added a few selfies with no filter at all.

In related news, Seohyun recently made her solo debut with the song "Don't Say No".
