One of Beyoncé's most well-known lyrics might be: "If you liked it, then you should have put a ring on it."

The 35-year-old singer stopped her concert in St. Louis on Saturday during the popular song "Single Ladies" to allow a concertgoer to do just that -- put a ring on it.

"I think (there's) somebody I need to bring on the stage," Beyoncé said during the song, prompting unsuspecting fans to scream in the hopes that they'd be chosen to join her.

"Is it you?" she teased, pointing to one audience member. "Is it you?" she asked, pointing to another.

Before long, a man joined Beyonce and her two dancers onstage, and she handed him the microphone.

The man, John Silver, walked toward Ashley Everett, Beyoncé's lead dancer and dance captain, and embraced her.

"I feel like it's only right to come out here in front of my hometown and show you guys what the epitome of a young woman looks like," Silver told the crowd. "I know that you think don't I express my love to you in front of everybody, so I feel like what better time than now to do it in front of (a crowd of people)? ... Will you marry me?"

The couple embraced before being congratulated by Beyoncé.

"Let's see if you can do the choreography after that," she said.

Everett, who took a few moments to collect herself, got back into formation and finished the choreography to "Single Ladies," flashing her new ring while doing the movements.

According to her website, Everett, who dropped out of Julliard to dance on tour with Beyoncé, has danced with the singer for the last 8 years and has also shared the stage with Robin Thicke, Usher, Ciara, Ne-Yo, LaToya Jackson, Jennifer Lopez and Tina Turner
