SNSD went to Vietnam on 18th October for Arirang Festival Concert.

When Jessica was performing on the stage,a female fan walked near her and gave her a huge hug.SNSD performed Michael Jackson's "Heal The World" together with all the performers at the end of the event.

The female fan was holding a bunch of flowers and she walked near Jessica when the show almost ended.SNSD's members were so surprised with that incident.Jessica who has become the main character of the hugging incident is either shocked or happy,nobody tell.

The fan did that because she was too excited,it seems that SNSD are not only stealing male fans' heart,but as well as female fans'!
