Kelly Clarkson marries gay couple on New Year’s Eve

She’ll remember a moment like this for the rest of her life.

Kelly Clarkson can add the title of “wedding witness” to her impressive resume after the Grammy-winning singer helped marry a gay couple during her Las Vegas residency on New Year’s Eve.

In a video posted to X, the couple, who were identified as Bronx Health Sciences High School assistant principal Brian Artzt and Marcello Cialini, can be seen explaining to the “Since U Been Gone” singer that they wanted her to serve as a witness in their ceremony.

“Oh, it is tonight! With me,” Clarkson, 41, can be heard saying excitedly.

A third man, who was serving as the couple’s officiant, was then handed the “Breakaway” singer’s microphone and urged him to “say something.”

“We gather here today to celebrate with two lovely gentlemen who want to claim their love tonight forever,” the officiant began while Clarkson looked on with a massive smile and the crowd yelled its approval.

“Brian, do you take Marcello to be your lawful wedded husband forever till death do you part for the rest of your life,” the man asked prompting Brian to agree.

The officiant then turned to Marcello and asked the man the same question.

Affirming their commitment to each other, the officiant then declared: “By the power of Kelly Clarkson’s show, Las Vegas, New Year’s 2024, I pronounce you both husband and husband.”

The “Stronger” singer then wished the newlyweds good luck before returning to her performance.

The Post has reached out to Artzt and Clarkson for comment.

Several online fans went wild at the very public wedding ceremony.

“Congrats to Bronx Health Sciences High School’s very own Assistant Principal Artzt on tying the knot—with an assist from @kellyclarkson—over winter break,” the New York Public Schools posted on X.

“She’s literally the sweetest omg,” another fan added.

“Such a heartwarming and inclusive moment! Kudos to Kelly Clarkson for celebrating love and spreading joy,” a third fan said.

Clarkson’s residency, “Chemistry: An Intimate Evening with Kelly Clarkson,” which celebrates “The Voice” alum’s album of the same name opened at the Bakkt Theater in July.

The residency is slated to end in February.

Recently, the singer was nominated for two Daytime Emmy Awards for Outstanding Daytime Talk Series and another for Outstanding Daytime Talk Series Host for her talk show “The Kelly Clarkson Show.”
