For those who don't know, Seulgi of the SMROOKIES had previously been called 'Kyuhyun's girl' after he talked about her and showed his support on 'Radio Star'. He later took to Twitter to clarify that she was not his girl.

On this week's 'Radio Star', the issue arose again as comedian and actress Kim Seul Gi revealed to everyone's amusement that when she first heard the stories, she thought she was the 'Seulgi' in question rather than the SM Entertainment rookie of the same name.

She talked about her confusion, "One day, 'Seulgi' was up on the real-time searches. There were even articles of 'Kyuhyun's girl'... So I thought Kyuhyun had talked about me, but it turned out to be someone else," making everyone laugh.

Kyuhyun said, "I heard a lot of complaints because I mentioned a trainee from my agency that time. But now they say I can mention her as much as I want."
