Jeff Probst, Katie Couric

It wasn't exactly a match made in heaven for talk show hosts Katie Couric and Jeff Probst, who both admitted that they once went on a date.

"I went out with Jeff Probst once," Couric told Howard Stern earlier this week. "I think he had puka shells on -- that was kind of a weird thing."

Celeb couples: Can you believe they dated?!

Shortly after Couric spilled about the date, Probst revealed the backstory to Us Weekly.

"Katie and I were set up by a mutual friend several years ago," he told the magazine. "What I remember most about the date is how nervous I was and how little I offered to the conversation. It was like I forgot how to go on a date. Like I was 14. We talked a bit about her kids and the challenges of being a parent to teenagers, and we talked a bit about our careers and lifestyles but we never got much beyond the surface."

So was there a second date?

"[I] would have definitely asked for a second date [but] the only reason I didn't call back was the date was set up through her assistant and I never got her number!" he says. "It felt weird to call her assistant for a second date," he said. "So it never had a chance to be a romance. Who knows what might have been? But it's a date I definitely remember! I mean, come on, it's Katie Couric!"

Couric, whose husband died of colon cancer in 1998, has not been shy about her dating history. In February, she told Jimmy Kimmel she had been out with Larry King on the most awkward date ever. (Watch her tell the story here.)

Fortunately for Couric, she's now happily dating financier John Molner. Probst, meanwhile, married Lisa Ann Russell in 2011.
