Let it be noted, Beyonce is good to her fans. Maybe a little too good. The mama-to-be was performing "Halo" and made the mistake of letting a tone-deaf fan finish the verse, which resulted in the punched-in-the-groin/pleasure-moan hybrid you hear above.
Thanks to the unidentifiable sound that came out of her mouth, it's safe to say this musically-challenged fan effectively blew her fifteen minutes seconds of fame.
But she had no choice! They were making her sing!
