The fake tape first surfaced on The Howard Stern Show Wednesday and has since been dismissed as "a complete prank," Matt Lauer told Knowles on Thursday morning's Today show.
"I haven't heard this, but I do know whoever did this did it as a joke," the singer, 27, told Lauer, who described the recording as a combination of "dogs barking and fingernails on a chalkboard."
She added, "I heard it's a little over the top."
What amazed her, said the Cadillac Records and Obsessed star, was that such a recording could go from someone's home – where the tape was created – to the nation's airwaves.
