The talk show host joked about her dramatic weight loss during a performance at her Las Vegas residency, Chemistry … an Intimate Night With Kelly Clarkson.

“Oh, boy. I really can’t bend in these,” she said as she tried to grab a mini bottle of vodka from a concertgoer, per a Tuesday TikTok video.

“Dude, this is tight,” she went on. “Like, I lost weight and they’re like, ‘Let’s get you into this tight s – – t.’”

The “American Idol” Season 1 winner then chugged the drink as a fan yelled from the crowd: “Skinny legend!”

Clarkson, who had been showing off a much smaller frame in recent months, opened up about her transformation for the first time in People’s latest cover story.

“Walking in the city is quite the workout. I’m really into infrared saunas right now. And I just got a cold plunge because everybody wore me down,” she said.

As for her diet, “I eat a healthy mix,” she explained.

“I dropped weight because I’ve been listening to my doctor — a couple years I didn’t,” she went on. “And 90% of the time I’m really good at it because a protein diet is good for me anyway. I’m a Texas girl, so I like meat — sorry, vegetarians in the world!”

The singer still does “splurge,” however, joking that she recently had a frozen yogurt with her daughter River Rose, 9, which “was magical.”

The former “Voice” coach hasn’t revealed how many pounds she’s actually lost, but in 2018 she did tell Today’s Hoda Kotb that she dropped 37 pounds at the time.

“I know the industry loves the weight gone, but for me, it wasn’t really the weight,” she said.

Clarkson also made headlines recently for taking part in a gay couple’s marriage ceremony at her residency on New Year’s Eve.

As she made her way into the crowd, the couple’s officiant, Phil Beniamino, was urged to “say something” while using Clarkson’s microphone.

“We gather here today to celebrate with two lovely gentlemen who want to claim their love tonight forever,” Beniamino began, while Clarkson watched. “By the power of Kelly Clarkson’s show, Las Vegas, New Year’s 2024, I pronounce you both husband and husband.”

The newlyweds were identified as Bronx Health Sciences High School assistant principal Brian Artzt and Marcello Cialini.

“It still doesn’t feel real,” Artzt exclusively told The Post in an interview Wednesday. “The shock is very much still in both of us.”

“[We] loved her from the moment we saw her on ‘American Idol,’” the newlyweds explained.

“Our first meeting ended up being all about Kelly,” Artzt gushed. “She was basically all we talked about. We barely got to know each other that night.”
