Some people can hold it. Kelly Clarkson is not one of those people.

Kelly was performing in Germany on Friday night when she mysteriously disappeared from the stage during a song. The band covered for her for a bit before she finally returned. She finished the song and then admitted, "I'm really sorry, I had to pee."

Such a lady.
