On pooping in a bucket during a concert…

Kelly was asked if she had ever peed herself during a performance. That hadn’t happened to her. However, she did go to the bathroom on stage.

“I had food poisoning twice in 20 years. Once was in Germany. I destroyed that bathroom. It was like Bridesmaids, and then I mean… sweat, everything. I was like ‘Something’s wrong deep down.’ Then Staples Center. Not many people have been cheered on while s-itting. And I have. Take that,” she joked.
