Singer IU made a surprise visit to actress Yoo In Na without telling her company.

In the middle of DJing her radio program KBS 2FM's 'Yoo In Na's Turn Up the Volume' on June 11th, DJ Yoo In Na suddenly yelled, "Oh my goodness!" in surprise.

The reason for her shock was that singer IU, who wasn't even scheduled to be on the show, had suddenly entered the radio booth.

"What is this, I'm so surprised," Yoo In Na remarked, to which IU responded, "I took a cab. If my managers find out, I'm in big trouble," revealing that she had snuck out without telling anyone.

IU continued, "The security at KBS is no joke. I took off my hat, but [the security officer] didn't recognize me because I didn't have makeup on."

"He asked what I was doing here so I told him I was IU, and all he said was 'Huh?'," IU explained, causing Yoo In Na to explode into laughter.

The singer brought a special 'sexy outfit' for Yoo In Na who recently celebrated a birthday, causing the actress/DJ to become embarrassed. Yoo In Na made a promise to wear the outfit during a live web broadcast of 'Turn Up the Volume'.

Because IU was not a planned guest, she was only supposed to speak on air for about 10 minutes. "Don't discipline me," IU begged her agency. Yoo In Na added, "Let's just pretend this never happened. We'll keep it between us."

Despite the fact that she could possibly get into trouble, IU ended up hosting the program alongside Yoo In Na for an hour, and the DJ seemed to be in a more giddy mood as she read stories from the listeners, making it apparent that she was glad to have IU around.
