The past dating rumor between actor So Ji Sub and After School's Jooyeon came up on Mnet's 'Beatles Code 3D' on April 15 as MBLAQ's G.O was present on the show and had been involved in the rumor, as well.  He was linked to this scandal as the alleged person who connected the two together.

The MCs said, "We heard that G.O got very angry when the dating rumor between So Ji Sub and Jooyeon came out."

G.O explained, "I was close to Jooyeon since [I was in] TYKEYS.  While I was eating with Jooyeon, So Ji Sub called me up," which is how the three ended up sitting together. He continued, "Words about that grew and grew until it came out in the news that I introduced the two.  I was greatly criticized during that period and called 'Introducer G.O.'"

Also on this day, G.O said, "While promoting as MBLAQ, I did not date even once," which caused Lee Joon to make a sound of disbelief that got the whole studio laughing.
