Jay Leno Busts Randy Jackson for Putting Hot Girls Through on 'American Idol' (VIDEO)

First of all, if your voice slips up about ten octaves and you're not singing, you might be trying to hide something. Such was the case with Randy Jackson, when he tried to vehemently deny that he would ever put a contestant through based on looks over voice on 'American Idol.' But 'The Tonight Show' (Weeknights, 11:35PM ET on NBC) had verifiable proof.

At least they had Jennifer Lopez backing up Leno's claim. After a simply okay female singer gave her audition, Steven Tyler gave a quick "yes," but Jennifer didn't think she was vocally ready. Randy couldn't keep his eyes off of her and when it came down to his vote, she went through.

"Seriously, you two?" Lopez asked at the time. "Seriously?"

"Busted!" Leno said now. "Busted!"
