Who's the latest in our endless parade of celebrities?

Chris Noth and Julianne Nicholson will answer your questions as partners, just like they do on Law & Order: Criminal Intent. Submit by September 25 to be included, then check back at our Ask the Stars area for their video response.

Then get ready for John Stamos, the newest full-time cast member of ER. Want to ask him what's disasters will befall the ill-fated Chicago hospital this season? Will an airplane fall? Will a bomb go off? Who else will be leaving? Or do you want to ask him about those pesky Olsen twins...It's your choice. He's there for you. Just get your questions in by September 26.

Want to see how it works? We've got answers from Matthew Perry, Bradley Whitford, Steve Carell and Megan Mullally in our Ask the Stars area.
