Kelly Clarkson — bringing couples together one song at a time.

From proposals to vow renewals, the "Breakaway" singer led a night of love in Las Vegas on Friday (November 7) in her first Studio Sessions residency concert at The Colosseum at Caesars Palace since taking time away following the death of her ex-husband Brandon Blackstock, per People.

The first moment came when she brought attention to a fan's proposal by the stage. In a video shared online, a man can be seen kneeling on the ground and holding out a ring as his boyfriend held his hands in front of his face and Clarkson excitedly looked on, holding out the microphone and encouraging them "speak louder."

After asking the all-important question, "Will you marry me?", Clarkson told the other man to "Say 'yes,' b----!" He did as he was told, replying,"Yes, b----!" as the crowd cheered and his now-fiancé slipped the ring on his finger before they shared a kiss. As Clarkson remarked that the proposal was "so sweet," the newly-engaged couple made sure to let her know she is "invited to the wedding now."

However, the show must go on and so Clarkson prefaced the next track with a warning for the couple that it doesn't have a happy ending, joking, "do me a favor and ignore this next song."

"Just stay in this moment, just hang out there, you know what I'm saying? Maybe go to the bathroom," she said, adding the song starts with a happy relationship "but then it ends [very differently]."

The happy couple weren't the only lovebirds to share a special moment during the show. Another couple decided to renew their vows to each other after 10 years of marriage and got Clarkson to join in on the nuptials.

According to another video shared online, one of the fans gave her sheet of their vows to read after Clarkson exclaimed, "You made it a decade? F--- yeah, look at that!" After making sure they realized she couldn't legally officiate anything, and hilariously throwing shade at her fellow The Voice coach alum Blake Shelton, she began to lead them through their vows.

"Do you both promise to keep dancing through life together — this is amazing! — offbeat or not, for at least another 10 years?" she asked, leading them to reply, "We do." "Then by the power of Kelly Clarkson's Vegas magic and your 10 years of love, I now pronounce you still married and still awesome."
