Kelly Clarkson is slaying this week, really and truly.

In an interview with Heat Magazine, the "Since You've Been Gone" singer was asked to address comments criticizing her weight made by Katie Hopkins, a controversial British television personality.

Clarkson responded with shade worthy of RuPaul's Drag Race when she told the magazine: "I don't have a clue what you're talking about. Someone tweeted something about me?" After having Hopkins' comments relayed to her, Clarkson continued to be laugh it off. "Oh, and she tweeted something nasty about me? That's because she doesn't know me. I'm awesome! It doesn't bother me. It's a free world. Say what you will."

American Idol stars: Where are they now?

"I've never cared what people think," she continued. "It's more if I'm happy and I'm confident and feeling good; that's always been my thing. And more so now, since having a family - I don't seek out any other acceptance."

Clarkson continued to charm the world Thursday night when she appeared on Watch What Happens Live. The Idol alum got candid during a round of Plead the Fifth, shutting down rumors that she had called Miley Cyrus a "pitchy stripper" during the VMAs. "I never said Miley Cyrus! The fact that I tweeted 'pitchy stripper' and people thought Miley Cyrus is not my problem. I'm just saying!" Clarkson said.

"I am not saying who it was because if I say it's not, then you're going to guess somebody else! You're trying to manipulate me! I'm going to drink more. Soon I'll say the truth, and then I can blame it on the alcohol!"

During the broadcast, Clarkson also admitted to having dated her From Justin to Kelly co-star Justin Guarini. "We didn't date during Idol, which everybody thought we were dating. We did date during... I feel like we weren't dating during the movie. But I feel like maybe we did. We did date a little bit," Clarkson explained. "I think any two people who are thrown together that much [would eventually date]. 'Timeless,' you put that song on From Justin to Kelly--you can't fight it!"
