Clarkson, 36, stunned at the event in Universal City, Calif., on May 17.
The American Idol champion has been open about battling her weight in the past. "There are just some people who are born skinny and with a great metabolism — that is not me,” she said in 2015. “I wish I had a better metabolism.”
Surprisingly, the singer isn’t shy about interest in her fitness ups and downs. "I think it's very important for me to be very open about my weight and people asking about it,” she has said.
Clarkson admitted in 2016 that having children had an impact on her shape: “I had two kids," she noted. "I felt like I was perfect for three years. And I didn't want to lose the weight back then, I knew I was gonna have another kid."
But no matter what she weighs, it shouldn’t matter, she has insisted."Too skinny, too fat, too blonde — so much blah. This is who I am and I'm happy. Happy looks different on everyone."
