JLO is NOT a singer, she's a lipsyncer. She NEVER sings live without some type of magic behind the stage enhancing her voice, whether it be pre-recorded vocals, backup singers that sing along with her voice to make it sound better when she's supposed to be going at it alone, or a microphone that she's able to turn on and off. I've seen her lipsync on stage to pre-recorded vocals through a mic and then its like she switched on the mic so you could hear her own voice.

JLO is a PRO at lypsincing. She knows all the tricks.

I have also heard her gasp for air ( she was ridiculed for that when she sang live at the Grammy's with Marc Anthony) at times because she's not singing from her diaphram like she's supposed to, which causes her to be out of breath and sound nasally.

Bottome Line, JLO has always been a studio created singer because if that woman could really sing and sound decent on her own, there is NO WAY , and I mean no way she would have picked a song like "Louboutins (using the excuse she's dancing) and "lypsync" each time (Ellen, SYTYCD, AMA's) on national TV knowing this is supposed to be her " big musical "comeback".
