A record of marriage registration signed by Jo Kwon is becoming an issue.

In the cable channel Y-STAR "Gag Six" scheduled to air on July 15, it was revealed that Jo Kwon's passionate fan received Jo Kwon's actual signature on a marriage registration form and had turned it in to have it legalized.

This was from 2009, when 2AM was promoting the song "A Friend's Confession," when this fanatic fan had gotten Jo Kwon's signature on a marriage registration form. She was stalking Jo Kwon to have him sign the marriage registration when he would be too busy to check what he is signing.

But according to the staff of "Gag Six", this marriage registration was not legalized.
