During last week's broadcast of MBC's 'Radio Star', MBLAQ's Lee Joon had made a surprise appearance to surprise his on-screen wife Oh Yeon Seo.

This week's broadcast of 'We Got Married' showed some unseen footage of Lee Joon's visit and revealed some questions the MCs had asked that did not make it onto the actual 'Radio Star' episode shown last week.

During the recording Lee Joon was asked, "Why are you so indifferent towards Oh Yeon Seo off screen?"

He responded to the question saying, "There is a reason" and looking over at Oh Yeon Seo he stated, "I'm really going to say it" and revealed, "Oh Yeon Seo called me in the middle of the night", shocking Oh Yeon Seo with his unexpected revealing and sparking the curiosity of all on set.
