Kelly Clarkson is used to people criticizing her weight, but that doesn't mean she's listening.

After the "Heartbeat Song" singer made an appearance on British TV’s “The Graham Norton Show,” Sun columnist Katie Hopkins tweeted repeated, disgusting comments about the singer’s figure. Kelly got on outpouring of love from supporters, but said that having her weight talked about is nothing new to her.

"I love that people think that's new. Like, welcome to the past 13 years," Kelly said during an appearance on the "The Ellen DeGeneres Show." "People are like, 'I'm so sorry that lady in London was so mean to you.' And I'm like, 'Are you serious?' Like, get in line!"

Kelly revealed that people started talking about her body when she was on "American Idol" since she was "the biggest girl" in the competition.

"I wasn't big, but people would call me big," she said.

And while she's developed a tolerance against all the body-shamers, she does admit that she feels for all of her fans who struggle with their image and encourages everyone to just be who they are.

"I think what hurts my feelings for people is when I'll have a meet and greet after the show and a girl whose, like, bigger than me will be in the meet and greet and be like, 'Oh, God!' And they'll say, 'If they think you're big, I must be so fat to them,'" she said. "It's like, you just are who you are. We are who we are -- whatever size. It doesn't mean that we're gonna be that forever. That's the thing! Sometimes we're more fit. Like, especially me. I'm such a creative person that I yo-yo. Sometimes I'm more fit and I get into kickboxing hardcore. And then sometimes I don't and I'm like, 'I'd rather have wine.'"

Toast to that!
