Leeteuk was a guest on MBC Music's 'All the K-Pop'.

On the show, he talked about his upcoming enlistment, stating, "I'll safely finish my army life and come back as a man." He tried to be stoic, but couldn't help but tear up when Boom and Shindong showed up. However, he got up immediately and managed to brighten up the  mood of the show again with his usual variety skills.

A few hours before the episode aired, Leeteuk tweeted, "I'm going to shave my hair now.. I thought of this song.. It was a song I sang a lot when I was little.. Shave your hair bald....... I only look good with my hair.. I'm ruined kekekekekekekekekekekekeke".

Leeteuk will reveal his shaved hair during the filming for 'Star King' on the 29th, which is also Kang Ho Dong's return episode.
