Super Junior Leeteuk knew about the SM couples before they went public.

On the October 8th episode of 'Radio Star,' Leeteuk along with three more Super Junior members were guests of the show. During this episode, the members were not able to escape the hard-hitting questions asked by the MCs - particularly Kim Gu Ra.

The topic of SM Entertainment artists who have coupled off was discussed with leader Leeteuk as he had previously revealed that he knew about Girls' Generation members YoonA and Sooyoung dating before the relationships went public.

As for f(x)'s Sulli and her relationship with Dynamic Duo rapper Choiza, Kim Gu Ra asked Leeteuk if he was involved in her dating affairs. During the time their relationship began, Leeteuk was still serving in the Korean Army; so his response was, "I had no hand in that area."

Going back to the Girls' Generation members, Leeteuk said did not feel good speaking about the matter because it was not his business to get involved in their dating lives.

Kim Gu Ra said, "Then tell us about your business."

Flustered, Leeteuk spoke instead about YoonA and Lee Seung Gi's relationship and how he played a role when it came to bringing the two lovebirds together.  "Lee Seung Gi said he wanted to meet up," Leeteuk said, but then spoke no further.

What do you think? Did Leeteuk bring YoonA and Lee Seung Gi together?
