For a performer, there's nothing like standing on stage and hearing the roar of the crowd. The same can't really be said for those times when that roar turns into what can only be described as a wounded moan -- the kind of thing you'd expect to hear out of an injured dog or a sad chimpanzee.

Unfortunately for Beyoncé Knowles, that's just what she was treated to when she  took the mic into the crowd at a recent concert in London and handed off singing duties to a particularly excited fan.

It's just a hunch but something tells us this fan might not quite have the "X-Factor." Listen to this Beyoncé fan sing below, and tell us what kind of animal she sounds like. We're thinking grizzly bear.
