The new season doesn't premiere until January, but Idol is already filming for Hollywood week, in which more than 300 people are vying for just 24 spots.
While everyone is hoping to find the next superstar, not all of the hopefuls are able to put their best foot forward in the audition room. J. Lo told us that she has a secret signal for her fellow judges when she thinks a singer is really tanking.
"I just pinch them," said J. Lo.
While J. Lo's been on the road for AI auditions, there have been rumors that she could soon be taking up residency in Las Vegas. Lance cleverly tried to see if there was any truth to the rumors.
"If there was one city you could spend a couple of years performing in what would it be?" asked Lance.
"I was thinking New York, but I think you're talking about someone else," J. Lo said with a laugh. "We have no announcement to make right now."
Rumors spread last week that the Grammy winner is in talks to do 72 shows in Sin City over the course of one or two years.
If J. Lo did do a Vegas residency, she would be the second pop diva to make the move in recent memory.
Britney Spears is currently in the middle of her two-year run at Planet Hollywood with her show Britney: Piece of Me, for which she reportedly makes $310,000 per performance.
