Ever since she won the first season of “American Idol” back in 2002, Kelly Clarkson has been massively successful in both the music and talk show worlds. Unfortunately, the 38 year-old star has also had to deal with body shamers who have critiqued her weight in both nasty and hurtful ways.

Clarkson, however, has never been one to let body shamers walk all over her, and she hasn’t been afraid to clap back at them through the years. During an interview with the tennis star Serena Williams, who has also had to deal with her fair share of body shaming, on her show this week, Clarkson made a point of thanking the athlete for being so “body positive.”

“I’ve always had to stand strong for myself with my body image in the public eye, and I love that you’ve always done that,” Clarkson said. “You are so body positive.”

Williams responded by commending Clarkson on how she’s always clapped back at her haters.

“I love that you’ve always done that,” said Williams, 39. “It’s so cool. One time, I think you went off on somebody. I was like, ‘Oh!’ I loved you for it.”

“Was that the British chick?” Clarkson responded, referring to a 2015 incident in which the British television personality, Katie Hopkins, questioned if the singer ate “all of her backing singers”.

“She doesn’t know me. I’m awesome! It doesn’t bother me,” Clarkson later told Heat magazine. “I was like, ‘Look, I ain’t got time for you over the pond.’ I got enough people hating on me over here!”

Clarkson went on to explain why she feels it’s important to discuss this kind of thing publicly.

“What makes me mad about it, [is] not how it’s said to me — it’s rude and obviously, nobody likes to hear it — but it’s because other women and other little girls are looking out there and they’re bigger than me and they’re going, ‘If they think she’s this way, then what does the world think of me?’” she explained. “The domino effect of that is so detrimental for people’s psyche and especially nowadays with young women on social media.”

“It’s just so hard, so that’s what makes me mad and I feel like I have to keep talking about it every once in a while and stand up,” Clarkson added, going on to say that while she tries to clap back in a funny way, “sometimes you just gotta shut it down.”
