Gwen Stefani, Jennifer Lopez: Set to Judge American Idol

The big news on American Idol last night wasn't which contestants were leaving - but which stars were coming.

The full lineup of guest judges were announced and it's none too shabby.

We'll start with Jennifer Lopez, who is rumored to both perform and serve as a guest judge. There's no word on whether or not the show will convert to Scientology for the evening.

Next, Gwen Stefani will serve on the panel for a night. Will there be yodeling involved? Tune in and find out! We also hope she brings along Kingston. That kid is a cutie.

Other stars that will sit alongside Simon, Randy and Paula in the future include:

• Jon Bon Jovi
• Martina McBride
• Diana Ross

Finally, men everywhere can be content that Antonella Barba moved on last night. You'll have at least one more week to admire this singer's beauty.
