The 'On the Floor' hitmaker performed on the ITV talent show on May 28 wearing a black bodysuit that flashed her bottom cheeks, reported Digital spy.
"I think people are so much raunchier than I am. I feel like I'm so tame. We wore it at Billboard and Britain's Got Talent said they wanted exactly the same. So I thought I'd wear the outfit in black.
"No-one complained at Billboard. I think people just like to talk. It was a body suit. A lot of performers wear that these days. It is standard stage clothes. I'm not going to walk down the street like that!," she said.
