NEW YORK -

Former "Seinfeld" stars Jerry Seinfeld and Jason Alexander were recently spotted outside the iconic restaurant from the TV show.

During a radio interview with WFAN's Bommer & Carton Seinfeld confirmed Alexander wasn't the only Seinfeld alum at the restaurant. Show regulars including co-creator Larry David, who took on an off-camera role for the event, were also there.

During the interview Seinfeld cleared up rumors that it's all for a Super Bowl ad or maybe the latest installment of his Web series, "Comedians in Cars Getting Coffee."

"It's neither," he said before blurring things further. "But it is not not those things, either. It's a secret project."

"I gave you more now than I’ve given anyone,” Seinfeld said when they balked at his answer. "I told you what it isn’t. And then I also told you that it isn’t not that, either."
