Kyuhyun received curious stares after his mother revealed his secret on this week's episode of KBS' 'Mamma Mia.'

Kyuhyun guest starred with his mother who looked relaxed as she made her first TV appearance. During the show, she also revealed that her son dresses very casually at home.

The MCs asked her if he just wears his boxers around the house and Kyuhyun's mother just nodded in reply. Then, they asked her if he wears panties and she didn't give a direct answer which made the viewers wonder what Kyuhyun actually wears at home.

Kyuhyun made others laugh as he told his mother, "Mom, if you do that, I sound like a nudist."

Meanwhile, Kyuhyun's mother also shared, "My child can't get plastic surgery to make the eyes longer because his eyes are close together like mine." She also added, "When he comes home, he hugs me and dances and gives me a kiss."

The two showed the viewers how close they were by dancing together and giving each other a kiss.
