BTOB's member Minhyuk's pants ripped during a live performance.

On Mnet "M! Countdown" aired on Thursday, group BTOB appeared and performed their new song "It's Okay."

But during the performance, as the members were powerfully doing their dance moves, Minhyuk's pants ripped in the middle, revealing his red boxers. Minhyuk seemed shocked at the fact that his pants ripped but he continued to dance and finish the song. But he could not hide in his laughter throughout the rest of the song, bringing laughter to the viewers as well.

After the show, Minhyuk posted on his Twitter, "It was the boxers that my manager brought for me... He said he was contemplating between the leopard print and this one... ah.... why..."
