IU was humiliated by her armpit hair.

In MBC "Three Wheels" aired today, IU came out as a special MC.

The MCs started talking about shaving in the bathroom, and somehow brought up that IU shaves too.

At this, IU said, "That's why I don't wear sleeveless shirts that often," and the MCs said, "So you don't shave...," arousing laughter.
