The internet prankster who made Beyonce Knowles sound out-of-tune has apologised for the hoax that "got out of hand".
Matthew Zeghibe tampered with a recording of the superstar performing on live TV last November (08) to make it sound like she is tone deaf.
The audio was leaked online and quickly grabbed the attention of fans, internet bloggers and shock jock Howard Stern, who aired the recording on his U.S. radio show.
The controversy prompted Knowles' father Mathew to dismiss the tape as a fake, and finally Zeghibe came forward to confess his scam.
The art student is stunned his creation attracted so much attention, telling Rolling Stone magazine, "It was just for a good laugh. It was a goof, just for fun. I do a lot of parodies on my YouTube channel, and it just so happens this one got a little out of hand."
But Zeghibe insists there's a serious side to his musical tampering - he claims it shows how easy it is to manipulate singers' voices to make them sound better and worse.
He adds, "I was just trying to make a point. I wanted to show people how easy it is to manipulate someone's voice. If I can do it with a clip I pulled off of TV, imagine what they are doing on records and during live performances. The entire industry has been so manipulated, because there's such an emphasis on perfection, so when something like this happens, it causes such a stir."
