While Stacy (Fergie) Ferguson and actor Josh Duhamel make final preparations for their weekend nuptials, Extra host Mario Lopez can’t wait to share in their happy day, people.com reports.

And Lopez has a special bond with Fergie: Both were one other’s first kiss in the ’80s, when they starred on Kids Incorporated.

“It’s a true story. I’m very proud of my first kiss,” says Lopez. “She says there was no tongue!”

But there was a romance, albeit brief, for the youngsters. “I wrote her a note and, as she likes to point out, I was very smooth at 10 because I bought her perfume,” Lopez says, laughing. “I think the gesture was pretty good for a kid.”

Once the young romance fizzled, a friendship blossomed. “I’m happy to say Stacy has stayed just as sweet as when we were kids,” Lopez says.
