Shock jock radio personality Howard Stern found joy in "exposing" Beyonce as he ran a leaked audio clip of the diva belting out some awkward notes in an unedited "board mix" from her 2008 'Today Show' appearance. In the clip, the singer/actress seemingly struggles through her hit 'If I Were a Boy' off her latest album, 'I Am ... Sasha Fierce.'

It's not clear whether portions of the audio were doctored to make the always-poised songbird sound less than perfect, but we can attest that Beyonce's voice was flawless when she took over AOL Music's New York studio in November. Despite feeling under the weather, Beyonce hit every note when she performed the singles 'Single Ladies' and 'If I Were a Boy' off her latest album, along with a few oldies but goodies, including 'Irreplaceable' and 'Me Myself and I.' The singer even treated us to an amazing performance of Etta James' 'At Last.'
