A practice track from a studio session where Jennifer Lopez was apparently trying to cover Barbra Streisand's Enough is Enough was leaked to the web, and we gotta say, not nearly as bad as you'd think!

If it even IS J. Lo (and the talking voice def sounds like her), at least she was aware when she was off-key and even sounding pretty darn good when she was on it!

Check it out above and tell us, do YOU think it's her?
