T-ara’s Jiyeon has been criticized for her stage manners during the group’s performance on KBS’s “Concert 7080” on December 26th.

Viewers have been expressing their disappointment with her blank face, and the insincere manner of how she performed the choreography.

Jiyeon appeared aloof through both performances of “Yayaya” and “Like An Indian Doll“, which eventually lead to KBS’s message board being flooded with discontented viewers.

One viewer commented, “I don’t know whether Jiyeon had personal issues, but she’s still a celebrity and it was uncomfortable watching her.  She really needs to become more professional.“  Others wrote, “T-ara needs to write an apology…,” and “I thought Jiyeon was a pro, but it seems I was wrong.  Was the 7080 concert not important enough for her?”

Online community site Instiz has also uploaded a video of the broadcast, heating up the controversy even further.

Core Contents Media addressed the issue with the following statement: “We haven’t checked anything regarding the issue, nor have we checked the message board.”

Jiyeon still a student.
Hormones are 'developing'.

PMS... 

Wow the photo, really - -

Lol Jiyeon of course PMS. Or exams?

More often times than not, atleast 1 girl member of any female idol group will have a PMS stage through a promotion.
Nothing new. So not an excuse.
Exams already over 3 weeks ago lol.
