On the St. Louis, Missouri stop of her Formation World Tour, queen of the universe Beyoncé Knowles stopped in the middle of "Single Ladies" to help two of her back-up dancers become single no more. On Sunday night, instead of inviting up fans from the audience during the song (like she did on the opening night of her tour), Beyoncé surprised her dance captain, Ashley Everett, by inviting up Everett's boyfriend (and fellow Beyoncé back-up dancer) John Silver. And then in front of thousands of screaming fans, Silver proceeded to, oh yes, put a ring on it.
