The marriage proposal happened during the singer's performance of her 'Put a ring on it' hit song.
Her boyfriend, John Silver, who reportedly performs with the likes of Ne-Yo and Chris Brown, made an unexpected appearance at the live show, by bending the knee and proposing to the dancer.
Silver couldn't have picked a better hour for his proposal, as it was a time when Beyonce was performing her 'Put a ring on it' hit song with the group.
The strange entrance made the show much more interesting as fans screamed in wild frenzy, evidently entertained by what went down on stage.
In one of the most heart melting wedding proposal, Silver said, "She's my queen, so I feel like it's only right to come out here in my hometown and show you guys the epitome of a young woman that knows how to deal with all the nonsense and the B.S. of a St. Louis n---a."
