Oops she did it again.  Jennifer Lopez dropped the F bomb during Jena Irene's performance of The King's 'Can't Help Falling In Love' on American Idol.

This isn't the first time Lopez has had producers rushing to edit. She let one slip a few months ago, ironically after a Jena performance.

Nice way to cap off the night for JLo, who demonstrated how to own the stage. Nice cat walk!

The performance was so good, I'd pay to hear it again. I think Elvis may have too. Jena should have closed the show. No one could follow that.

See JLo's slip is at the 1:20 mark.

Rocker Caleb Johnson gave Jena a run for her money and I expect them to be in the final two. He opened the show with Bon Jovi's 'You Give Love A Bad Name' and finished with Keith Urban and Nicole Kidman's favorite song 'Maybe I'm Amazed.' The only thing better than Caleb's performances is Keith's reaction to them.

Jessica Meuse and Alex Preston provide so-so, predictable performances. At least Alex showed some emotion when he sang. Maybe he could give Jessica tips. I have a feeling she'll be the one sent home tonight. Find out on Fox at 9pm.
