Girl group 4Minute's member HyunA put on lipstick in the middle of a show, arousing controversy.

In Mnet "Beatles Code 3D" aired on March 25, 4Minute came out as guests.

When asked about dating restrictions on 4Minute from the agency, HyunA said, "There weren't any restrictions to begin with. Our CEO actually encourages us to date." But while she was saying this, she took out her lipstick and put it on so naturally.

MC Shin Dong Yup, who seemed shocked at first, said, "This is what I like. She looks so comfortable," laughing, and copied her actions of putting on lipstick.

Internet users who saw this commented, "I got shocked too", "Is she allowed to do that while filming?", and "That would've been a huge issue if Shin Dong Yup didn't play it off well like that".
